+# API Style Guide
+
+This guide provides the basic structure for creating OpenSearch API documentation. It includes the various elements that we feel are most important to creating complete and useful API documentation, as well as description and examples where appropriate.
+
+Depending on the intended purpose of the API, *some sections will be required while others may not be applicable*.
+
+Use the [API_TEMPLATE](templates/API_TEMPLATE.md) to create an API documentation page.
+
+### A note on terminology ###
+
+Terminology for API parameters varies in the software industry, where two or even three names may be used to label the same type of parameter. For consistency, we use the following nomenclature for parameters in our API documentation:
+* *Path parameter* – "path parameter" and "URL parameter" are sometimes used synonymously. To avoid confusion, we use "path parameter" in this documentation.
+* *Query parameter* – This parameter name is often used synonymously with "request parameter." We use "query parameter" to be consistent.
+
+### General usage for code elements
+
+When you describe any code element in a sentence, such as an API, a parameter, or a field, you can use the noun name. 
+  *Example usage*:
+  The time field provides a timestamp for job completion.
+
+When you provide an exact example with a value, you can use the code element in code font. 
+  *Example usage*: 
+  The response provides a value for `time_field`, such as “timestamp.” 
+
+Provide a REST API call example in `json` format. Optionally, also include the `curl` command if the call can only be executed in a command line.
+
+## Basic elements for documentation
+
+The following sections describe the basic API documentation structure. Each section is discussed under its respective heading. Include only those elements appropriate to the API. 
+
+Depending on where the documentation appears within a section or subsection, heading levels may be adjusted to fit with other content.
+
+1. Name of API (heading level 2)
+1. (Optional) Path and HTTP methods (heading level 3)

+1. Example request (heading level 4)
+1. Example response (heading level 4)
+1. Response fields (heading level 3)
+
+## API name
+
+Provide an API name that describes its function, followed by a description of its top use case and any usage recommendations.
+
+*Example function*: "Autocomplete queries"
+
+Use sentence capitalization for the heading (for example, "Create or update mappings"). When you refer to the API operation, you can use lowercase with code font.
+
+If there is a corresponding OpenSearch Dashboards feature, provide a “See also” link that references it. 
+*Example*: “To learn more about monitor findings, see [Document findings](https://opensearch.org/docs/latest/monitoring-plugins/alerting/monitors/#document-findings)."
+
+If applicable, provide any caveats to its usage with a note or tip, as in the following example:
+
+"If you use the Security plugin, make sure you have the appropriate permissions."
+(To set this point in note-style format, follow the text on the next line with {: .note})
+
+### Path and HTTP methods
+
+For relatively complex API calls that include path parameters, it's sometimes a good idea to provide an example so that users can visualize how the request is properly formed. This section is optional and includes examples that illustrate how the endpoint and path parameters fit together in the request. The following is an example of this section for the nodes stats API:
+
+```json
+GET /_nodes/stats
+GET /_nodes/<node_id>/stats
+GET /_nodes/stats/<metric>
+GET /_nodes/<node_id>/stats/<metric>
+GET /_nodes/stats/<metric>/<index_metric>
+GET /_nodes/<node_id>/stats/<metric>/<index_metric>
+```
+
+### Path parameters
+
+While the API endpoint states a point of entry to a resource, the path parameter acts on the resource that precedes it. Path parameters come after the resource name in the URL.
+
+In the following example, the resource is `scroll` and its path parameter is `<scroll_id>`:
+
+```json
+GET _search/scroll/<scroll_id>
+```
+
+Introduce what the path parameters can do at a high level. Provide a table with parameter names and descriptions. Include a table with the following columns:
+*Parameter* – Parameter name in plain font.
+*Data type* – Data type capitalized (such as Boolean, String, or Integer).
+*Description* – Sentence to describe the parameter function, default values or range of values, and any usage examples.
+
+Parameter | Data type | Description
+:--- | :--- | :---
+
+### Query parameters
+
+In terms of placement, query parameters are always appended to the end of the URL and located to the right of the operator "?". Query parameters serve the purpose of modifying information to be retrieved from the resource.
+
+In the following example, the endpoint is `aliases` and its query parameter is `v` (provides verbose output):
+
+```json
+GET _cat/aliases?v
+```
+
+Include a paragraph that describes how to use the query parameters with an example in code font. Include the query parameter operator "?" to delineate query parameters from path parameters.
+
+For GET and DELETE APIs: Introduce what you can do with the optional parameters. Include a table with the same columns as the path parameter table.
+
+Parameter | Data type | Description
+:--- | :--- | :---
+
+### Request fields
+
+For PUT and POST APIs: Introduce what the request fields are allowed to provide in the body of the request.
+
+Include a table with these columns: 
+*Field* – Field name in plain font.
+*Data type* – Data type capitalized (such as Boolean, String, or Integer).
+*Description* – Sentence to describe the field’s function, default values or range of values, and any usage examples.
+
+Field | Data type | Description
+:--- | :--- | :--- 
+
+#### Example request
+
+Provide a sentence that describes what is shown in the example, followed by a cut-and-paste-ready API request in JSON format. Make sure that you test the request yourself in the Dashboards Dev Tools console to make sure it works. See the following examples.
+
+The following request gets all the settings in your index:
+
+```json
+GET /sample-index1/_settings
+```
+
+The following request copies all of your field mappings and settings from a source index to a destination index:
+
+```json
+POST _reindex
+{
+   "source":{
+      "index":"sample-index-1"
+   },
+   "dest":{
+      "index":"sample-index-2"
+   }
+}
+```
+
+#### Example response
+
+Include a JSON example response to show what the API returns. See the following examples.
+
+The `GET /sample-index1/_settings` request returns the following response fields: 
+
+```json
+{
+  "sample-index1": {
+    "settings": {
+      "index": {
+        "creation_date": "1622672553417",
+        "number_of_shards": "1",
+        "number_of_replicas": "1",
+        "uuid": "GMEA0_TkSaamrnJSzNLzwg",
+        "version": {
+          "created": "135217827",
+          "upgraded": "135238227"
+        },
+        "provided_name": "sample-index1"
+      }
+    }
+  }
+}
+```
+
+The `POST _reindex` request returns the following response fields: 
+
+```json
+{
+  "took" : 4,
+  "timed_out" : false,
+  "total" : 0,
+  "updated" : 0,
+  "created" : 0,
+  "deleted" : 0,
+  "batches" : 0,
+  "version_conflicts" : 0,
+  "noops" : 0,
+  "retries" : {
+    "bulk" : 0,
+    "search" : 0
+  },
+  "throttled_millis" : 0,
+  "requests_per_second" : -1.0,
+  "throttled_until_millis" : 0,
+  "failures" : [ ]
+}
+```
+
+### Response fields
+
+For PUT and POST APIs: Define all allowable response fields that can be returned in the body of the response.
+
+Field | Data type | Description
+:--- | :--- | :---

+
+# Contributing guidelines
+
+Thank you for your interest in improving the OpenSearch documentation! We value and appreciate all feedback and contributions from our community, including requests for additional documentation, corrections to existing content, and reports of technical issues with the documentation site. 
+
+You can [create an issue](#creating-an-issue) asking us to change the documentation or [contribute content](#contributing-content) yourself.
+
+NOTE: If you’d like to contribute but don't know where to start, try browsing existing [issues](https://github.com/opensearch-project/documentation-website/issues). Our projects use custom GitHub issue labels for status, version, type of request, and so on. We recommend starting with any issue labeled "good first issue" if you're a beginner or "help wanted" if you're a more experienced user. 
+
+## Creating an issue
+
+Use the documentation issue template to describe the change you'd like to make:
+
+1. Go to https://github.com/opensearch-project/documentation-website/issues and select **New issue**.
+1. Enter the requested information, including as much detail as possible, especially which version or versions the request affects.
+1. Select **Submit new issue**. 
+
+The `untriaged` label is assigned automatically. During the triage process, the Documentation team will add the appropriate labels, assign the issue to a technical writer, and prioritize the request. We may follow up with you for additional information. 
+
+## Contributing content
+
+There are two ways to contribute content, depending on the magnitude of the change:
+
+- [Minor changes](#making-minor-changes): For small changes to existing files, like fixing typos or adding parameters, you can edit files in GitHub directly. This approach does not require cloning the repository and does not allow you to test the documentation.
+- [Major changes](#making-major-changes): For changes you want to test first, like adding new or reorganizing pages or adding a table or section, you can edit files locally and push the changes to GitHub. This approach requires setting up a local version of the repository and allows you to test the documentation.
+
+### Contribution workflow
+
+The workflow for contributing documentation is the same as the one for contributing code:
+
+- Make your changes.
+- Build the documentation website to check your work (only possible if you are making changes locally).
+- Submit a [pull request](https://github.com/opensearch-project/documentation-website/pulls) (PR).
+- A maintainer reviews and merges your PR.
+
+### Before you start
+
+Before contributing content, make sure to read the following resources:
+- [README](README.md)
+- [OpenSearch Project Style Guidelines](STYLE_GUIDE.md)
+- [API Style Guide](API_STYLE_GUIDE.md)
+- [Formatting Guide](FORMATTING_GUIDE.md) 
+
+NOTE: Make sure that any documentation you submit is your own work or work that you have the right to submit. We respect the intellectual property rights of others, and as part of contributing, we'll ask you to sign your contribution with a [Developer Certificate of Origin (DCO)](https://github.com/opensearch-project/.github/blob/main/CONTRIBUTING.md#developer-certificate-of-origin) stating that you have the right to submit your contribution and that you understand that we will use your contribution. 
+
+### Making minor changes
+
+If you want to make minor changes to an existing file, you can use this approach:
+
+1. [Fork this repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo).
+
+1. In your fork on GitHub, navigate to the file that you want to change.
+
+1. In the upper-right corner, select the pencil icon and edit the file.
+
+1. In the upper-right corner, select **Commit changes...***. Enter the commit message and optional description and select **Create a new branch for this commit and start a pull request**.
+
+### Making major changes
+
+If you're adding a new page or making major changes to the documentation, such as adding new images, sections, or styling, we recommend that you work in a local copy of the repository and test the rendered HTML before submitting a PR. 
+
+#### Setting up your local copy of the repository
+
+Follow these steps to set up your local copy of the repository:
+
+1. [Fork this repository](https://docs.github.com/en/get-started/quickstart/fork-a-repo) and clone your fork.
+
+1. Navigate to your cloned repository.
+
+1. Install [Ruby](https://www.ruby-lang.org/en/) if you don't already have it. We recommend [RVM](https://rvm.io/), but you can use any method you prefer:
+
+   ```
+   curl -sSL https://get.rvm.io | bash -s stable
+   rvm install 3.2
+   ruby -v
+   ```
+
+1. Install [Bundler](https://bundler.io/) if you don't already have it:
+
+   ```
+   gem install bundler
+   ```
+
+1. Install Jekyll and all the dependencies:
+
+   ```
+   bundle install
+   ```
+
+#### Making, viewing, and submitting changes 
+
+Here's how to build the website, make changes, and view them locally:
+
+1. Build the website:
+
+   ```
+   sh build.sh    
+   ```
+
+   The build script should automatically open your web browser, but if it doesn't, open [http://localhost:4000/docs/](http://localhost:4000/docs/).
+
+1. Create a new branch against the latest source on the main branch. 
+
+1. Edit the Markdown files that you want to change.
+
+1. When you save a file, Jekyll automatically rebuilds the site and refreshes your web browser. This process can take 60--90 seconds.
+
+1. When you're happy with how everything looks, commit, [sign off](https://github.com/src-d/guide/blob/9171d013c648236c39faabcad8598be3c0cf8f56/developer-community/fix-DCO.md#how-to-prevent-missing-sign-offs-in-the-future), push your changes to your fork, and submit a PR.
+
+    Note that a PR requires DCO sign-off before we can merge it. You can use the -s command line option to append this automatically to your commit message, for example, `git commit -s -m 'This is my commit message'`. For more information, see https://github.com/apps/dco.
+
+## Review process
+
+We greatly appreciate all contributions to the documentation and will review them as quickly as possible. 
+
+During the PR process, expect that there will be some back-and-forth. If you want your contribution to be merged quickly, try to respond to comments in a timely fashion, and let us know if you don't want to continue with the PR. 
+
+We use the [Vale](https://github.com/errata-ai/vale) linter to ensure that our documentation adheres to the [OpenSearch Project Style Guidelines](STYLE_GUIDE.md). Addressing Vale comments on the PR expedites the review process. You can also install Vale locally so you can address the comments before creating a PR. For more information, see [Style linting](#style-linting).
+
+If we accept the PR, we will merge it and will backport it to the appropriate branches.
+
+### Style linting
+
+To ensure that our documentation adheres to the [OpenSearch Project Style Guidelines](STYLE_GUIDE.md), we use the [Vale](https://github.com/errata-ai/vale) linter. Addressing Vale comments on the PR expedites the review process. You can also install Vale locally as follows so you can address the comments before creating a PR:
+
+1. Run `brew install vale`.
+2. Run `vale *` from the documentation site root directory to lint all Markdown files. To lint a specific file, run `vale /path/to/file`.
+
+Optionally, you can install the [Vale VSCode](https://github.com/chrischinchilla/vale-vscode) extension, which integrates Vale with Visual Studio Code. By default, only _errors_ and _warnings_ are underlined. To change the minimum alert level to include _suggestions_, go to **Vale VSCode** > **Extension Settings** and select **suggestion** in the **Vale > Vale CLI: Min Alert Level** dropdown list.

+
+## Adding pages or sections
+
+This repository contains [Markdown](https://guides.github.com/features/mastering-markdown/) files organized into Jekyll _collections_ (for example, `_api-reference` or `_dashboards`). Each Markdown file corresponds to one page on the website.
+
+In addition to the content for a given page, each Markdown file contains some Jekyll [front matter](https://jekyllrb.com/docs/front-matter/) similar to the following:
+
+```
+---
+layout: default
+title: Date
+nav_order: 25
+has_children: false
+parent: Date field types
+grand_parent: Supported field types
+---
+```
+
+If you want to reorganize content or add a new page, make sure to set the appropriate `has_children`, `parent`, `grand_parent`, and `nav_order` variables, which define the hierarchy of pages in the left navigation. 
+
+When adding a page or a section, make the `nav_order` of the child pages multiples of 10. For example, if you have a parent page `Clients`, make child pages `Java`, `Python`, and `JavaScript` have a `nav_order` of 10, 20, and 30, respectively. Doing so makes inserting additional child pages easier because it does not require you to renumber existing pages.
+
+Each collection must have an `index.md` file that corresponds to the collection's index page. In the `index.md` file's front matter, specify `nav_excluded: true` so that the page does not appear separately under the collection.
+
+## Buttons
+
+You can use either `copy` or `copy-curl` includes for code snippets. The `copy` include places a **Copy** button on the code snippet, while the `copy-curl` include places both **Copy** and **Copy as cURL** buttons. Use the `copy-curl` include for API requests. If an API request is already in the cURL format, use the `copy` include.
+
+**Example of a `copy` include**
+
+````
+```bash
+curl -XGET "localhost:9200/_tasks?actions=*search&detailed
+```
+{% include copy.html %}
+````
+
+**Example of a `copy-curl` include**
+
+````
+```json
+PUT /sample-index1/_clone/cloned-index1
+{
+  "aliases": {
+    "sample-alias1": {}
+  }
+}
+```
+{% include copy-curl.html %}
+````
+
+## Callouts
+
+You can use four levels of callouts:
+
+*  `{: .note}` blue
+*  `{: .tip }` green
+*  `{: .important}` yellow
+*  `{: .warning}` red
+
+Place a callout directly under the paragraph to which you want to apply the callout style.
+
+**Example**
+
+```
+In case of a cluster or node failure, all PIT data is lost.
+{: .note}
+```
+
+For a callout with multiple paragraphs or lists, use `>`:
+
+```
+>   ****PREREQUISITE****
+>
+>   To use a custom vector map with GeoJSON, install these two required plugins:
+>   * OpenSearch Dashboards Maps [`dashboards-maps`](https://github.com/opensearch-project/dashboards-maps_) front-end plugin
+>   * OpenSearch [`geospatial`](https://github.com/opensearch-project/geospatial_) backend plugin
+{: .note}
+
+```
+
+## Collapsible blocks
+
+To insert an open collapsible block, use the `<details>` element as follows:
+
+````html
+<details open markdown="block">
+  <summary>
+    Response
+  </summary>
+  {: .text-delta}
+
+```json
+{
+  "_nodes" : {
+    "total" : 1,
+    "successful" : 1,
+    "failed" : 0
+  }
+}
+```
+</details>
+````
+
+To insert a closed collapsible block, omit the `open` state:
+
+````html
+<details markdown="block">
+  <summary>
+    Response
+  </summary>
+  {: .text-delta}
+
+```json
+{
+  "_nodes" : {
+    "total" : 1,
+    "successful" : 1,
+    "failed" : 0
+  }
+}
+```
+</details>
+````
+
+Collapsible blocks are useful for long responses and for the Table of Contents at the beginning of a page.
+
+## Dashes
+
+Use one dash for hyphens, two for en dashes, and three for em dashes:
+
+```
+upper-right
+10--12 nodes per cluster
+There is one candidate generator available---`direct_generator`.
+```
+
+## Horizontal rule
+
+A horizontal rule is used to separate text sections. Use three asterisks separated by spaces for a horizontal rule:
+
+```
+## Why use OpenSearch?
+
+* * *
+```
+
+## Images
+
+Place images in the `images` directory of the documentation website. To refer to images, use relative links (see [Internal links](#internal-links) for more information).
+
+Markdown images are responsive by default. To insert a Markdown image, use the `![<alternate text>](link)` syntax:
+
+```
+![OS branding]({{site.url}}{{site.baseurl}}/images/brand.png)
+```
+
+Markdown uses the image’s actual width to render it. It sets the maximum image width to the width of the main body panel.
+
+If you want to specify the image width or another style, use HTML syntax:
+
+```
+<img src="{{site.url}}{{site.baseurl}}/images/brand.png" alt="OS branding" width="700"/>
+```
+
+You can specify width as a hard-coded number of pixels, as in the preceding example, or as a percentage of the parent width:
+
+```
+<img src="{{site.url}}{{site.baseurl}}/images/brand.png" alt="OS branding" width="70%"/>
+```
+
+To stretch the image to fit the width of the main body panel, use width=“100%”.
+
+To take high-resolution screenshots, in Firefox, right-click on the page and choose “Take Screenshot”.
+
+Image borders are automatic; do not manually add a border to an image.
+
+Always **separate an image from the text with a blank line**:
+
+```
+To send a query to OpenSearch, select the query by placing the cursor anywhere in the query text. Then choose the triangle on the top right of the request or press `Ctrl/Cmd+Enter`:
+
+<img src="{{site.url}}{{site.baseurl}}/images/dev-tools/dev-tools-send.png" alt="Send request">
+```
+
+Do not place an image next to text or insert artificial line breaks using `<br>`. Otherwise, the text might render as aligned to the bottom of the image, with the image on the right. 
+
+If the image is under a list item, place it on a new line with a tab. For more examples, see [Lists with code snippets or images](#lists-with-code-snippets-or-images).
+
+### Images in line with text
+
+When describing an icon, use the icon's name followed by an inline image in parentheses. Insert the image in line with text using the `nomarkdown` extension and an HTML image:
+
+```
+Choose the play icon ({::nomarkdown}<img src="{{site.url}}{{site.baseurl}}/images/dev-tools/play-icon.png" class="inline-icon" alt="play icon"/>{:/}) on the upper right of the request.
+```
+
+## Labels
+
+You can use the following labels:
+
+* label-blue 
+* label-green
+* label-purple 
+* label-red 
+* label-yellow 
+
+Use a purple label to specify the version in which an API was introduced:
+
+```
+# Alias
+Introduced 1.0
+{: .label .label-purple }
+```
+
+If we introduce a breaking change to an operation, add an additional label with a link to the release note for that breaking change:
+
+```
+## Get roles
+Introduced 1.0
+{: .label .label-purple }
+[Last breaking change 2.0](https://example.com)
+{: .label .label-red }
+```
+
+## Links
+
+To add a link to a document, section, or image, use the `[name](link)` syntax, for example:
+
+```
+## Looking for the Javadoc?
+
+See [opensearch.org/javadocs/](https://opensearch.org/javadocs/).
+```
+
+### Section links
+
+**Section links** are links to headings in your document. Markdown lowercases the headings for links, drops back ticks, and replaces spaces with hyphens:
+
+```
+## The `minimum_should_match` parameter
+
+For more information, see [the `minimum_should_match` parameter](#the-minimum_should_match-parameter).
+```
+
+### Internal links
+
+**Internal links** are links to another document or image within the documentation website. Because the documentation website is versioned, do not hard code the version number in the link. Use the relative path, where `{{site.url}}{{site.baseurl}}` refers to the main directory, instead:
+
+```
+If you need to use a field for exact-value search, map it as a [`keyword`]({{site.url}}{{site.baseurl}}/opensearch/supported-field-types/keyword/).
+```
+
+### GitHub links
+
+When linking to a GitHub issue or PR, refer to the issue or PR number in the following format:
+
+```
+For more details, see issue [#1940](https://github.com/opensearch-project/opensearch/issues/1940).
+```
+
+## Lists
+
+Markdown supports unordered and ordered lists, nested lists, and lists with code snippets or images.
+
+### Unordered lists
+
+Use asterisks or dashes for unordered lists:
+
+```
+* One
+* Two
+```
+
+or
+
+```
+- One 
+- Two
+```
+
+Lists with dashes render the list items closer to each other vertically, while lists with asterisks have more space between the lines.
+
+Don’t mix and match asterisks and dashes.
+
+### Ordered lists
+
+Use all 1s for ordered lists:
+
+```
+1. One 
+1. Two
+```
+
+Jekyll will automatically correctly number the items, and it will be much easier for you to insert and delete items without renumbering.
+
+If there is a paragraph in the middle of a list, the list will restart with 1 after the paragraph. If you want to continue the list after the paragraph, use `counter-reset: none`:
+
+```
+1.  One
+
+Paragraph that breaks the numbering
+
+{:style="counter-reset: none"}
+1.  Two
+```
+
+### Nested lists
+
+Use tabs to nest lists:
+
+```
+1. Parent 1
+    - Child 1
+    - Child 2
+        - Grandchild 1
+```
+
+Markdown automatically adjusts numbered lists so that they use numbers and letters, so always use 1s for nested numbered lists. 
+
+### Lists with code snippets or images
+
+If you need to position an image or a code snippet within a list, use tabs to signal to Markdown that the image or code snippet is part of the list item.
+
+**Example with code snippets**
+
+```
+1. Run the demo batch script.
+   There are two ways of running the batch script:
+   1. Run the batch script using the Windows UI:
+      1. Navigate to the top directory of your OpenSearch installation and open the `opensearch-{{site.opensearch_version}}` folder.
+      1. Run the batch script by double-clicking the `opensearch-windows-install.bat` file. This opens a command prompt with an OpenSearch instance running.
+   1. Run the batch script from Command prompt or Powershell:
+      1. Open Command Prompt by entering `cmd`, or Powershell by entering `powershell`, in the search box next to ****Start**** on the taskbar. 
+      1. Change to the top directory of your OpenSearch installation.
+         ```bat
+         cd \path\to\opensearch-{{site.opensearch_version}}
+         ```
+      1. Run the batch script.
+         ```bat
+         .\opensearch-windows-install.bat
+         ```
+```
+
+**Example with images**
+
+```
+1. To begin, select the rule in the **Rule name** column. The rule details pane opens, as shown in the following image.
+    <img src="{{site.url}}{{site.baseurl}}/images/Security/rule-dup2.png" alt="Opening the rule details pane" width="50%">
+
+1. Select the **Duplicate** button in the upper-right corner of the pane. The **Duplicate rule** window opens in Visual Editor view, and all of the fields are automatically populated with the rule's details. Details are also populated in YAML Editor view, as shown in the following image.
+    <img src="{{site.url}}{{site.baseurl}}/images/Security/dupe-rule.png" alt="Selecting the duplicate button opens the Duplicate rule window" width="50%">
+```
+
+## Math
+
+To add mathematical expressions to a page, add `has_math: true` to the page’s front matter. Then insert LaTeX math into HTML tags with the rest of your Markdown content, as shown in the following example:
+
+```
+## Math
+
+Some Markdown paragraph. Here's a formula:
+
+<p>
+  When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
+  \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
+</p>
+
+And back to Markdown.
+```
+
+## Tables
+
+Markdown table columns are automatically sized, and there is no need to specify a different number of dashes in the formatting. 
+
+**Example**
+
+```
+Header 1 | Header 2
+:--- | :---
+Body 1 | Body 2, which is extremely lengthy, but there is no need to specify its width.
+```
+
+To insert line breaks within tables, use `<br>`:
+
+```
+Header 1 | Header 2
+:--- | :---
+Body 1 | Body paragraph 1 <br> Body paragraph 2 
+```
+
+To use lists within a table, use `<br>` and `-` :
+
+```
+Header 1 | Header 2
+:--- | :---
+Body 1 | List:<br>- One<br>- Two
+```
+
+
+You can also use `&nbsp;` to insert one space, `&ensp;` to insert two spaces, and `&emsp;` to insert four spaces in table cells.
+
+If you need a list with real bullet points, use the bullet point HTML code:
+
+```
+Header 1 | Header 2
+:--- | :---
+Body 1 | List:<br>&ensp;&#x2022; One<br>&ensp;&#x2022; Two
+```
+
+## Text style
+
+You can style text in the following ways:
+
+* ```**bold**```
+* ```_italic_``` or ```*italic*```
+
+For guidance on using code examples and when to use code font, see [Code examples](https://github.com/opensearch-project/documentation-website/blob/main/STYLE_GUIDE.md#code-examples).
+
+## Variables in curly braces
+
+To correctly display variables that are in curly braces, escape the curly braces with the `{% raw %}{% endraw %}` tags:
+
+````
+"message_template": {
+    "source": "the index is {% raw %}{{ctx.index}}{% endraw %}"
+}
+````
+
+The variable `ctx.index` is rendered in double curly braces.
+
+## Videos
+
+To insert a video, add a YouTube player include similar to the following:
+
+```
+{% include youtube-player.html id='_g46WiGPhFs' %}
+```
+
+Note that the `id` variable refers to the YouTube video ID at the end of the URL. For example, the YouTube video at the URL `https://youtu.be/_g46WiGPhFs` has the ID `_g46WiGPhFs`. The ID must be surrounded with single quotation marks.

+# OpenSearch Project Style Guidelines
+
+Welcome to the content style guide for the OpenSearch Project. This guide covers the style standards to be observed when creating OpenSearch content and will evolve as we implement best practices and lessons learned in order to best serve the community.
+
+In addition to this guide and [TERMS.md](https://github.com/opensearch-project/documentation-website/blob/main/TERMS.md), our content is generally edited in accordance with the [Microsoft Writing Style Guide](https://docs.microsoft.com/en-us/style-guide/welcome/), [The Chicago Manual of Style](https://www.chicagomanualofstyle.org/home.html), and [Merriam-Webster](https://www.merriam-webster.com/) (listed in order of precedence); however, we may deviate from these style guides in order to maintain consistency and accommodate the unique needs of the community. This is by no means an exhaustive list of style standards, and we value transparency, so we welcome contributions to our style standards and guidelines. If you have a question regarding our standards or adherence/non-adherence to the style guides or would like to make a contribution, please tag @natebower on GitHub.
+
+## Naming conventions, voice, tone, and brand personality traits
+
+The following sections provide guidance on OpenSearch Project naming conventions, voice, tone, and brand personality traits.
+
+### Naming conventions
+
+The following naming conventions should be observed in OpenSearch Project content:
+
+* Capitalize both words when referring to the *OpenSearch Project*.
+* *OpenSearch* is the name for the distributed search and analytics engine used by Amazon OpenSearch Service.
+* Amazon OpenSearch Service is a managed service that makes it easy to deploy, operate, and scale OpenSearch. Use the full name *Amazon OpenSearch Service* on first appearance. The abbreviated service name, *OpenSearch Service*, can be used for subsequent appearances.
+* Amazon OpenSearch Serverless is an on-demand serverless configuration for Amazon OpenSearch Service. Use the full name *Amazon OpenSearch Serverless* on first appearance. The abbreviated service name, *OpenSearch Serverless*, can be used for subsequent appearances. 
+* OpenSearch Dashboards is the UI for OpenSearch. On first appearance, use the full name *OpenSearch Dashboards*. *Dashboards* can be used for subsequent appearances.
+* *Security Analytics* is a security information and event management (SIEM) solution for OpenSearch. Capitalize both words when referring to the name of the solution.
+* Observability is collection of plugins and applications that let you visualize data-driven events by using Piped Processing Language (PPL). Capitalize *Observability* when referring to the name of the solution.
+* Refer to OpenSearch Project customers as *users*, and refer to the larger group of users as *the community*. Do not refer to the OpenSearch Project or to the AWS personnel working on the project as a *team*, as this implies differentiation within the community.
+
+#### Product names
+
+Capitalize product names. The OpenSearch Project has three products: OpenSearch, OpenSearch Dashboards, and Data Prepper. For example:
+
+* “To install *OpenSearch*, download the Docker image.”
+* “To access *OpenSearch Dashboards*, open your browser and navigate to http://localhost:5601/app/home.”
+* “*Data Prepper* contains the following components:”
+
+Capitalize the names of clients and tools. For example:
+
+* “The OpenSearch *Python* client provides a more natural syntax for interacting with your cluster.”
+* “The *Go* client retries requests for a maximum of three times by default.”
+* “The *OpenSearch Kubernetes Operator* is an open-source Kubernetes operator that helps automate the deployment and provisioning of OpenSearch and OpenSearch Dashboards in a containerized environment.”
+* “You can send events to *Logstash* from many different sources.”
+
+#### Features
+
+Features are the individual building blocks of user experiences, reflect the functionality of a product, and are shared across different experiences. For example, the SQL/PPL, reporting, notifications, alerting, and anomaly detection used for observability are the same SQL/PPL, reporting, notifications, alerting, and anomaly detection used for general analytics, security analytics, and search analytics. Components of the user experience such as navigation, credentials management, theming, etc. are also considered to be features.
+
+Use lowercase when referring to features, unless you are referring to a formally named feature that is specific to OpenSearch. For example:
+
+* “The Notifications plugin provides a central location for all of your *notifications* from OpenSearch plugins.”
+* “*Remote-backed storage* is an experimental feature. Therefore, we do not recommend the use of *remote-backed storage* in a production environment.”
+* “You can take and restore *snapshots* using the snapshot API.”
+* “You can use the *VisBuilder* visualization type in OpenSearch Dashboards to create data visualizations by using a drag-and-drop gesture” (You can refer to VisBuilder alone or qualify the term with “visualization type”).
+
+#### Plugin names
+
+A plugin is a feature or distinct component that extends the functionality of OpenSearch. For now, capitalize plugin names, but use *plugin* sparingly. The concept of plugins will become obsolete once we re-architect the product. For example:
+
+* “Interaction with the *ML Commons* plugin occurs through either the REST API or [ad](https://opensearch.org/docs/latest/search-plugins/sql/ppl/functions#ad) and [kmeans](https://opensearch.org/docs/latest/search-plugins/sql/ppl/functions#kmeans) Piped Processing Language (PPL) commands.”
+* “Use the *Neural Search* plugin to integrate ML language models into your search workloads.”
+
+### Voice and tone
+
+Voice is the point of view or style of a writer. Voice can refer to active or passive but may also refer to verb tense (past, present, future, and so on). Tone is the emotional undercurrent (such as calm or angry) of the voice. We strive to speak to the community with a consistent voice and tone, as if a single writer writes all content. Writing with a common voice also helps to establish the OpenSearch Project identity and brand.
+
+#### Voice
+
+The voice of the OpenSearch Project is people oriented and focused on empowering the user directly. We use language that emphasizes what the user can do with OpenSearch rather than what tasks OpenSearch can perform.
+
+Whenever possible, use the active voice instead of the passive voice. The passive form is typically wordier and can often cause writers to obscure the details of the action. For example, change the agentless passive _it is recommended_ to the more direct _we recommend_.
+
+Refer to the reader as _you_ (second person), and refer to the OpenSearch Project as _we_ (first person). If there are multiple authors for a blog post, you can use _we_ to refer to the authors as individuals. Do not refer to the OpenSearch Project or to the AWS personnel working on the project as a *team*, as this implies differentiation within the community.
+
+In most cases, try to describe the actions that the user takes rather than contextualizing from the feature perspective. For example, use phrases such as “With this feature, you can...” or “Use this feature to...” instead of saying a feature *allows*, *enables*, or *lets* the user do something.
+
+For procedures or instructions, ensure that action is taken by the user (“Then you can stop the container...”) rather than the writer (“We also have to stop the container...”). Reserve the first-person plural for speaking as the OpenSearch Project, with recommendations, warnings, or explanations.
+
+In general, use the present tense. Use the future tense only when an event happens later than, not immediately after, the action under discussion.
+
+#### Tone
+
+The tone of the OpenSearch Project is conversational, welcoming, engaging, and open. The overall tone is knowledgeable but humble, informal but authoritative, informative but not dry, and friendly without being overly familiar.
+
+We talk to readers in their own words, never assuming that they understand how OpenSearch works. We use precise technical terms where appropriate, but we avoid technical jargon and insider lingo. We speak to readers in simple, plain, everyday language.
+
+Avoid excessive words, such as please. Be courteous but not wordy. Extra detail can often be moved elsewhere. Use humor with caution because it is subjective, can be easily misunderstood, and can potentially alienate your audience.
+
+### Brand personality traits
+
+| Personality trait | Description | Guidance |
+| :--------- | :------- | :------ |
+| **Clear and precise** | The OpenSearch Project understands that our community works, develops, and builds in roles and organizations that require precise thinking and thorough documentation. We strive to use precise language—to clearly say what we mean without leaving ideas open to interpretation, to support our assertions with facts and figures, and to provide credible and current (third-party) references where called for. <br> <br> We communicate in plain, direct language that is easily understood. Complex concepts are introduced in a concise, unambiguous way. High-level content is supported by links to more in-depth or technical content that users can engage with at their convenience. | - Write with clarity and choose words carefully. Think about the audience and how they might interpret your assertions. <br> - Be specific. Avoid estimates or general claims when exact data can be provided. <br> - Support claims with data. If something is “faster” or “more accurate,” say how much. <br> - When citing third-party references, include direct links. |
+| **Transparent and open** | As an open-source project, we exchange information with the community in an accessible and transparent manner. We publish our product plans in the open on GitHub, share relevant and timely information related to the project through our forum and/or our blog, and engage in open dialogues related to product and feature development in the public sphere. Anyone can view our roadmap, raise a question or an issue, or participate in our community meetings. | - Tell a complete story. If you’re walking the reader through a solution or sharing news, don’t skip important information. <br> - Be forthcoming. Communicate time-sensitive news and information in a thorough and timely manner. <br> - If there’s something the reader needs to know, say it up front. Don’t “bury the lede.” |
+| **Collaborative and supportive** | We’re part of a community that is here to help. We aim to be resourceful on behalf of the community and encourage others to do the same. To facilitate an open exchange of ideas, we provide forums through which the community can ask and answer one another’s questions. | - Use conversational language that welcomes and engages the audience. Have a dialogue. <br> - Invite discussion and feedback. We have several mechanisms for open discussion, including requests for comment (RFCs), a [community forum](https://forum.opensearch.org/), and [community meetings](https://www.meetup.com/OpenSearch/).
+| **Trustworthy and personable** | We stay grounded in the facts and the data. We do not overstate what our products are capable of. We demonstrate our knowledge in a humble but authoritative way and reliably deliver what we promise. We provide mechanisms and support that allow the audience to explore our products for themselves, demonstrating that our actions consistently match our words. <br> <br> We speak to the community in a friendly, welcoming, judgment-free way so that our audience perceives us as being approachable. Our content is people oriented and focused on empowering the user directly. | - Claims and assertions should be grounded in facts and data and supported accordingly. <br> - Do not exaggerate or overstate. Let the facts and results speak for themselves. <br> - Encourage the audience to explore our products for themselves. Offer guidance to help them do so. <br> - Write directly and conversationally. Have a dialogue with your audience. Imagine writing as if you’re speaking directly to the person for whom you’re creating content. <br> - Write from the community, for the community. Anyone creating or consuming content about OpenSearch is a member of the same group, with shared interest in learning about and building better search and analytics solutions. |
+| **Inclusive and accessible** | As an open-source project, the OpenSearch Project is for everyone, and we are inclusive. We value the diversity of backgrounds and perspectives in the OpenSearch community and welcome feedback from any contributor, regardless of their experience level. <br> <br> We design and create content so that people with disabilities can perceive, navigate, and interact with it. This ensures that our documentation is available and useful for everyone and helps improve the general usability of content. <br> <br> We understand our community is international and our writing takes that into account. We use plain language that avoids idioms and metaphors that may not be clear to the broader community. | - Use inclusive language to connect with the diverse and global OpenSearch Project audience. <br> - Be careful with our word choices. <br> - Avoid [sensitive terms](https://github.com/opensearch-project/documentation-website/blob/main/STYLE_GUIDE.md#sensitive-terms). <br> - Don't use [offensive terms](https://github.com/opensearch-project/documentation-website/blob/main/STYLE_GUIDE.md#offensive-terms). <br> - Don't use ableist or sexist language or language that perpetuates racist structures or stereotypes. <br> - Links: Use link text that adequately describes the target page. For example, use the title of the target page instead of “here” or “this link.” In most cases, a formal cross-reference (the title of the page you’re linking to) is the preferred style because it provides context and helps readers understand where they’re going when they choose the link. <br> - Images: <br> &nbsp;&nbsp;- Add introductory text that provides sufficient context for each image. <br> &nbsp;&nbsp;- Add ALT text that describes the image for screen readers. <br> - Procedures: Not everyone uses a mouse, so use device-independent verbs; for example, use “choose” instead of “click.” <br> - Location: When you’re describing the location of something else in your content, such as an image or another section, use words such as “preceding,” “previous,” or “following” instead of “above” and “below.”
+
+## Style guidelines
+
+The following guidelines should be observed in OpenSearch Project content.
+
+### Acronyms
+
+Spell out acronyms the first time that you use them on a page and follow them with the acronym in parentheses. Use the format `spelled-out term (acronym)`. On subsequent use, use the acronym alone.
+
+Do not capitalize the spelled-out form of an acronym unless the spelled-out form is a proper noun or the community generally capitalizes it. In all cases, our usage should reflect the community’s usage.
+
+In general, spell out acronyms once on a page. However, you can spell them out more often for clarity.
+
+Make an acronym plural by adding an *s* to the end of it. Do not add an apostrophe.
+
+How an acronym is pronounced determines whether you use the article *an* or *a* before it. If it's pronounced with an initial vowel sound, use *an*. Otherwise, use *a*.
+
+If the first use of an acronym is in a heading, retain the acronym in the heading, and then write out the term in the following body text, followed by the acronym in parentheses. Don't spell out the term in the heading with the acronym included in parentheses. If the first use of the service name is in a title or heading, use the short form of the name in the heading, and then use the long form followed by the short form in parentheses in the following body text.
+
+In general, spell out abbreviations that end with *-bit* or *-byte*. Use abbreviations only with numbers in specific measurements. Always include a space between the number and unit. Abbreviations that are well known and don't need to be spelled out are *KB*, *MB*, *GB*, and *TB*. 
+
+Some acronyms are better known than their spelled-out counterparts or might be used almost exclusively. These include industry-standard protocols, markdown and programming languages, and common file formats. You don't need to spell out these acronyms.
+
+The following table lists acronyms that you don't need to spell out.
+
+| Acronym | Spelled-out term |
+| :--------- | :------- |
+| 3D | three-dimensional |
+| AI | artificial intelligence |
+| API | application programming interface |
+| ASCII | American Standard Code for Information Interchange |

+| URI | uniform resource identifier |
+| URL | uniform resource locator |
+| UTC | Coordinated Universal Time |
+| UTF | Unicode Transformation Format |
+| XML | Extensible Markup Language |
+| YAML | YAML Ain't Markup Language |
+
+### Code examples
+
+Calling out code within a sentence or code block makes it clear to readers which items are code specific. The following is general guidance about using code examples and when to use `code font`:
+
+* In Markdown, use single backticks (`` ` ``) for inline code formatting and triple backticks (```` ``` ````) for code blocks. For example, writing `` `discovery.type` `` in Markdown will render as `discovery.type`. A line containing three backticks should be included both before and after an example code block.
+* In sentences, use code font for things relating to code, for example, “The `from` and `size` parameters are stateless, so the results are based on the latest available data.” 
+* Use lead-in sentences to clarify the example. Exception: API examples, for which a caption-style lead-in (heading 4) is sufficient. 
+* Use the phrase *such as* for brief examples within a sentence.
+* Use language-specific indentation in code examples.
+* Make code blocks as copy-and-paste friendly as possible. Use either the [`copy` or `copy-curl` buttons](https://github.com/opensearch-project/documentation-website/blob/main/FORMATTING_GUIDE.md#buttons).
+
+#### Code formatting checklist
+
+The following items should be in `code font`:
+
+* Field names, variables (including environment variables), and settings (`discovery.type`, `@timestamp`, `PATH`). Use code font for variable and setting values if it improves readability (`false`, `1h`, `5`, or 5).
+* Placeholder variables. Use angle brackets for placeholder variables (`docker exec -it <container-id> /bin/bash`).
+* Commands, command-line utilities, and options (`docker container ls -a`, `curl`, `-v`).
+* File names, file paths, and directory names (`docker-compose.yml`, `/var/www/simplesamlphp/config/`).
+* URLs and URL components (`localhost`, `http://localhost:5601`).
+* Index names (`logs-000001`, `.opendistro-ism-config`), endpoints (`_cluster/settings`), and query parameters (`timeout`).
+* Language keywords (`if`, `for`, `SELECT`, `AND`, `FROM`).
+* Operators and symbols (`/`, `<`, `*`).
+* Regular expression, date, or other patterns (`^.*-\d+$`, `yyyy-MM-dd`).
+* Class names (`SettingsModule`) and interface names (*`RestHandler`*). Use italics for interface names.
+* Text field inputs (Enter the password `admin`).
+* Email addresses (`[email protected]`).
+
+#### Caption-style examples
+
+If you use a caption-style example, use the heading **Example**, with a colon, as appropriate. The following are caption-style examples:
+
+   **Example: Retrieve a specified document from an index**
+
+   The following example shows a request that retrieves a specific document and its information from an index:
+
+   `GET sample-index1/_doc/1`
+
+   **Example request**
+
+   `GET sample-index1/_doc/1` 
+
+Sometimes, you might not want to break up the flow of the text with a new heading. In these cases, you can use an example with no heading.
+
+   The following command maps ports 9200 and 9600, sets the discovery type to single-node, and requests the newest image of OpenSearch:
+
+   `docker run -d -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:latest`
+
+#### Lead-in sentences
+
+When using lead-in sentences, summarize, clarify, or refer to the example that follows. A lead-in sentence is a complete sentence that ends in a colon.  
+
+   For example, the following query requests statistics for `docs` and `search`:
+
+   `GET _nodes/stats/indices/docs,search`
+
+#### Referring to a variable or placeholder
+
+When introducing a code or command line example that refers to a variable or placeholder in the example, be direct by including the variable or placeholder name in the text. Surround the variable or placeholder name with angle brackets (`<` and `>`), for example, `<port>`. Don't refer to the variable or placeholder by its color or format because these can change. If variable or placeholder texts have a lot in common and there are several for the user to complete, be direct by including a “template” for the input in the replaceable text.
+
+   In the following example, replace `<component-x>` with your own information:
+
+   `~/workspace/project-name$ eb init --modules <component-a> <component-b>`
+
+### Formatting and organization
+
+- Use a colon to introduce example blocks (for example, code and scripts) and most lists. Do not use a colon to introduce tables or images.
+
+- Use bold text for all UI elements, including pages, panes, and dialog boxes. In all cases, emphasize what the user must do as opposed to talking about the UI element itself.
+
+- Stacked headings should never appear in our content. Stacked headings are any two consecutive headings without intervening text. Even if it is just an introductory sentence, there should always be text under any heading.
+
+- Use italics for the titles of books, periodicals, and reference guides. However, do not use italics when the title of a work is also a hyperlink.
+
+- You can refer to APIs in three ways:
+     1. When referring to API names, capitalize all words in the name (example: "Field Capabilities API").
+     2. When referring to API operations by the exact name of the endpoint, use lowercase with code format (example: "`_field_caps` API").
+     3. When describing API operations but not using the exact name of the endpoint, use lowercase (example: "field capabilities API operations" or "field capabilities operations").
+
+### Images
+
+- Add introductory text that provides sufficient context for each image.
+
+- Add ALT text that describes the image for screen readers.
+
+- When you’re describing the location of an image, use words such as *preceding*, *previous*, or *following* instead of *above* and *below*.
+
+- Text that introduces an image should be a complete sentence and end with a period, not a colon.
+
+### Links
+
+- **Formal cross-references**: In most cases, a formal cross-reference (the title of the page you're linking to) is the preferred style because it provides context and helps readers understand where they're going when they choose the link. Follow these guidelines for formal cross-references:
+     - Introduce links with formal introductory text:
+          - Use "For information *about*" or "For more information *about*." Don't use "For information *on*."
+          - If you are linking to procedures, you can use either "For instructions *on*" or "instructions *for*." Don't use "instructions *about*."
+          - Where space is limited (for example, in a table), you can use "*See* [link text]."
+     - Ensure that the link text matches the section title text. <br> <br> Example: "To get involved, see [Contributing](https://opensearch.org/source.html) on the OpenSearch website." <br>
+
+- **Embedded links**: Embedded links are woven into a sentence without formal introductory text. They're especially useful in tables or other elements where space is tight. The text around the embedded link must relate to the information in the link so that the reader understands the context. Do not use *here* or *click here* for link text because it creates accessibility problems. <br> <br> Example: "Finally, [delete the index](https://opensearch.org/docs/latest/api-reference/index-apis/delete-index)."
+
+### Lists
+
+The following guidelines apply to all list types:
+- Make lists parallel in content and structure. Don’t mix single words with phrases, don’t start some phrases with a noun and others with a verb, and don’t mix verb forms.
+- Present the items in alphabetical order if the order of items is arbitrary.
+- Capitalize the first letter of the first word of each list item.
+- If the list is simple, you don’t need end punctuation for the list items.
+- If the list has a mixture of phrases and sentences, punctuate each list item.
+- Punctuate each list item with a period if a list item has more than one sentence.
+- Punctuate list items consistently. If at least one item in a list requires a period, use a period for all items in that list.
+- Introductory sentences are required for lists.
+- Introductory sentences should be complete sentences.
+- Introductory sentences should end with a colon.
+- Don’t use semicolons, commas, or conjunctions (like and or or) at the end of list items.
+
+### Numbers and measurement
+
+- Spell out cardinal numbers from 1 to 9. For example, one NAT instance. Use numerals for cardinal numbers 10 and higher. Spell out ordinal numbers: first, second, and so on. In a series that includes numbers 10 or higher, use numerals for all. Use a comma separator for numbers of four digits or more—for example, 1,000.
+
+- For descriptions that include time ranges, separate the numbers with an en dash. Avoid extra words such as between or from n to n.
+     - Correct: It can take 5–10 minutes before logs are available.
+     - Incorrect: It can take between 5 and 10 minutes before logs are available.
+
+- Use numerals for all measurement-based references, including time. Include a space between the number and the abbreviation for the unit of measure.
+     - Correct:
+        - 100 GB
+        - 1 TB
+        - 3 minutes
+        - 12 subnets (8 public and 4 private)
+     - Incorrect
+        - One hundred GB
+        - 1TB
+
+### Procedures
+
+A procedure is a series of numbered steps that a user follows to complete a specific task. Users should be able to scan for and recognize procedures easily. Make procedures recognizable by using the following:
+
+- Predictable content parts
+- Parallel language constructions
+- Consistent formatting
+
+Use *example*, not *sample*, to introduce example blocks (for example, code, scripts, and API requests and responses).
+
+#### Describing interactions with the UI
+
+Replace pointer-specific verbs with device-agnostic/generic verbs to accommodate readers with disabilities and users of various input methods and devices, including the pointer, keyboard, and touch screens. Don't use device-specific verbs such as _click_ or _swipe_. However, when the generic language makes it difficult to understand the instructions, you can include pointer-specific hints in parentheses. Use your judgment. If you have a question, ask your editor.
+
+We follow a slightly modified version of the _Microsoft Writing Style Guide_ guidance on describing interactions with a UI, provided here.
+
+| Verb | Use for | Examples |
+| :--------- | :------- | :------- |
+| **Open** | - Apps and programs <br> - Files and folders <br> - Shortcut menus <br> Use for websites and webpages only when necessary to match the UI. Otherwise, use _go to_. <br> - Don't use for commands and menus. | - Open Photos. <br> - Open the Reader app. <br> - Open the Filename file. <br> - To open the document in Outline view, select **View** > **Outline**. <br> - In WindowName, open the shortcut menu for ItemName. |
+| **Close** | - Apps and programs <br> - Dialog boxes <br> - Files and folders <br> - Notifications and alerts <br> - Tabs <br> - The action a program or app takes when it encounters a problem and can't continue. (Don't confuse with _stop responding_). | - Close the Alarms app. <br> - Close Excel. <br> - Save and close the document. <br> - Closing Excel also closes all open worksheets. |
+| **Leave** | Websites and webpages | Select **Submit** to complete the survey and leave this page. |
+| **Go to** | - Opening a menu. <br> - Going to a tab or another particular place in the UI. <br> - Going to a website or webpage. <br> - It's ok to use _On the **XXX** tab_ if the instruction is brief and continues immediately. | - Go to Search, enter the word **settings**, and then select **Settings**. <br> - Go to **File**, and then select **Close**. <br> - On the ribbon, go to the **Design** tab. <br> - Go to the **Deploy** tab. in the **Configuration** list ... <br> - On the **Deploy** tab, in the **Configuration** list ... <br> - Go to Example.com to register. |
+| **Select** | Instructing the user to select a specific item, including: <br> - Selecting an option, such as a button. <br> - Selecting a checkbox. <br> - Selecting a value from a list box. <br> - Selecting link text to go to a link. <br> - Selecting an item on a menu or shortcut menu. <br> - Selecting an item from a gallery. | - Select the **Modify** button. <br> - For **Alignment**, select **Left**. <br> - Select the text, open the shortcut menu, and then select **Font**. <br> - Select **Open in new tab**. <br> - Select the **LinkName** link. |
+| **Select and hold, select and hold (or right-click)** | Use to describe pressing and holding an element in the UI. It's OK to use _right-click_ with _select and hold_ when the instruction isn't specific to touch devices. | - To flag a message that you want to deal with later, select and hold it, and then select **Set flag**. <br> - Select and hold (or right-click) the Windows taskbar, and then select **Cascade windows**. <br> - Select and hold (or right-click) the **Start** button, and then select **Device Manager**. |
+| **>** | Use a greater-than symbol (>) to separate sequential steps. <br> Only use this approach when there's a clear and obvious path through the UI and the selection method is the same for each step. For example, don't mix things that require opening, selecting, and choosing. <br> Don't bold the greater-than symbol. Include a space before and after the symbol. | Select **Accounts** > **Other accounts** > **Add an account**. |
+| **Clear** | Clearing the selection from a checkbox. | Clear the **Header row** checkbox. | 
+| **Choose** | Choosing an option, based on the customer's preference or desired outcome. | On the **Font** tab, choose the effects you want. |
+| **Switch, turn on, turn off** | Turning a toggle key or toggle switch on or off. | - Use the **Caps lock** key to switch from typing capital letter to typing lowercase letters. <br> - To keep all applied filters, turn on the **Pass all filters** toggle. |
+| **Enter** | Instructing the customer to type or otherwise insert a value, or to type or select a value in a combo box. | - In the search box, enter... <br> - In the **Tab stop position** box, enter the location where you want to set the new tab. <br> - In the **Deployment script name** box, enter a name for this script. |
+| **Move, drag** | Moving anything from one place to another by dragging, cutting and pasting, or another method. Use for tiles and any open window (including apps, dialog boxes, and files). <br> Use _move through_ to describe moving around on a page, moving through screens or pages in an app, or moving up, down, right, and left in a UI. | - Drag the Filename file to the Foldername folder. <br> - Move the tile to the new section. <br> - Drag the Snipping Tool out of the way, if necessary, and then select the area you want to capture. <br> - If the **Apply Styles** task pane is in your way, just move it. |
+| **Press** | Use _press_ to describe single key or key combination entries that users would perform on a keyboard, such as keyboard shortcuts. | - Press **F5**. <br> - Press **Shift+Enter**. <br> - Press **Ctrl+Alt+Delete**. |
+| **Zoom, zoom in, zoom out** | Use _zoom_, _zoom in_, and _zoom out_ to refer to changing the magnification of the screen or window. | - Zoom in to see more details on the map. <br> - Zoom out to see a larger geographic area on the map. <br> - Zoom in or out to see more or less detail. |
+
+### Punctuation and capitalization
+
+- Use only one space after a period.
+
+- Use contractions carefully for a more casual tone. Use common contractions. Avoid future tense (I’ll), archaic (‘twas), colloquial (ain’t), or compound (couldn’t’ve) contractions.
+
+- Use sentence case for titles, headings, and table headers. Titles of standalone documents may use title case.
+
+- Use lowercase for nouns and noun phrases that are not proper nouns; for example, *big data*. This style follows the standard rules of American English grammar.
+
+- For plural forms of nouns that end in “s”, form the possessive case by adding only an apostrophe.
+
+- When a colon introduces a list of words, a phrase, or other sentence fragment, the first word following the colon is lowercased unless it is a proper name. When a colon introduces one or more complete sentences, the first word following it is capitalized. When text introduces a table or image, it should be a complete sentence and end with a period, not a colon.
+
+- Use commas to separate the following:
+     - Independent clauses separated by coordinating conjunctions (but, or, yet, for, and, nor, so).
+     - Introductory clauses, phrases, words that precede the main clause.
+     - Words, clauses, and phrases listed in a series. Also known as the Oxford comma.
+
+- An em dash (—) is the width of an uppercase M. Do not include spacing on either side. Use an em dash to set off parenthetical phrases within a sentence or set off phrases or clauses at the end of a sentence for restatement or emphasis.
+
+- An en dash (–) is the width of an uppercase N. In ranges, do not include spacing on either side. Use an en dash to indicate ranges in values and dates, separate a bullet heading from the following text in a list, or separate an open compound adjective (two compounds, only one of which is hyphenated) from the word that it modifies.
+
+- Words with prefixes are normally closed (no hyphen), whether they are nouns, verbs, adjectives, or adverbs. Note that some industry terms don’t follow this hyphenation guidance. For example, *Command Line Interface* and *high performance computing* aren’t hyphenated, and *machine learning* isn’t hyphenated when used as an adjective. Other terms are hyphenated to improve readability. Examples include *non-production*, *post-migration*, and *pre-migration*.
+
+- In general, comparative or superlative modifiers with “more,” “most,” “less,” or “least” don’t require hyphens. Use one only if it’s needed to avoid ambiguity.
+
+- The ampersand (&) should never be used in a sentence as a replacement for the word and. An exception to this is in acronyms where the ampersand is commonly used, such as in Operations & Maintenance (O&M).
+
+- When using a forward slash between words, do not insert space on either side of the slash. For example, *AI/ML* is correct whereas *AI / ML* is incorrect.
+
+- When referring to API parameters, capitalize *Boolean*. Otherwise, primitive Java data types (*byte*, *short*, *int*, *long*, *float*, *double*, and *char*) start with a lowercase letter, while non-primitive types start with an uppercase letter.
+
+### Topic titles
+
+Here are two styles you can use for topic titles:
+
+* *Present participle phrase* + *noun-based phrase* or *present participle phrase* + *preposition* + *noun-based phrase*, used most often for concept or task topics. For example:
+     * Configuring security
+     * Visualizing your data
+     * Running queries in the console
+
+* *Noun-based phrase*, used most often for reference topics. For example:
+     * REST API reference
+     * OpenSearch CLI
+     * Field types
+     * Security analytics
+
+Use *example*, not *sample*, in headings that introduce example blocks (for example, code, scripts, and API requests and responses).
+
+## UI text
+
+Consistent, succinct, and clear text is a critical component of a good UI. We help our users complete their tasks by providing simple instructions that follow a logical flow.
+
+### UI best practices
+
+* Follow the OpenSearch Project [naming conventions, voice, tone, and brand personality traits](#naming-conventions-voice-tone-and-brand-personality-traits) guidelines.
+* Be consistent with other elements on the page and on the rest of the site.
+* Use sentence case in the UI, except for product names and other proper nouns.
+
+### UI voice and tone
+
+Our UI text is people oriented and focused on empowering the user directly. We use language that is conversational, welcoming, engaging, and open and that emphasizes what the user can do with OpenSearch rather than what tasks OpenSearch can perform. The overall tone is knowledgeable but humble, informal but authoritative, informative but not dry, and friendly without being overly familiar.
+
+We talk to readers in their own words, never assuming that they understand how OpenSearch works. We use precise technical terms where appropriate, but we avoid technical jargon and insider lingo. We speak to readers in simple, plain, everyday language.
+
+For more information, see [Voice and tone](#voice-and-tone) and [Brand personality traits](#brand-personality-traits).
+
+### Writing guidelines
+
+UI text is a critical component of a user interface. We help users complete tasks by explaining concepts and providing simple instructions that follow a logical flow. We strive to use language that is consistent, succinct, and clear.
+
+#### What's the purpose of UI text?
+
+UI text includes all words, phrases, and sentences on a screen, and it has the following purposes:
+
+* Describes a concept or defines a term
+* Explains how to complete a task
+* Describes the purpose of a page, section, table, graph, or dialog box
+* Walks users through tutorials and first-run experiences
+* Provides context and explanation for individual UI elements that might be unfamiliar to users
+* Helps users make a choice or decide if settings are relevant or required for their particular deployment scenario or environment
+* Explains an alert or error
+
+#### Basic guidelines
+
+Follow these basic guidelines when writing UI text.
+
+##### Style
+
+* Keep it short. Users don’t want to read dense text. Remember that UI text can expand by 30% when it’s translated into other languages.
+* Keep it simple. Try to use simple sentences (one subject, one verb, one main clause and idea) rather than compound or complex sentences.
+* Prefer active voice over passive voice. For example, "You can attach up to 10 policies" is active voice, and "Up to 10 policies can be attached" is passive voice.
+* Use device-agnostic language rather than mouse-specific language. For example, use _choose_ instead of _click_ (exception: use _select_ for checkboxes).
+
+##### Tone
+
+* Use a tone that is knowledgeable but humble, informal but authoritative, informative but not dry, and friendly without being overly familiar.
+* Use everyday language that most users will understand.
+* Use second person (you, your) when you address the user.
+* Use _we_ if you need to refer to the OpenSearch Project as an organization; for example, "We recommend…."
+
+##### Mechanics
+
+* Use sentence case for all UI text. (Capitalize only the first word in a sentence or phrase as well as any proper nouns, such as service names. All other words are lowercase.)
+* Use parallel construction (use phrases and sentences that are grammatically similar). For example, items in a list should start with either all verbs or all nouns.
+     
+     **Correct**
+
+     Snapshots have two main uses:
+     * Recovering from failure
+     * Migrating from one cluster to another
+
+     **Incorrect**
+
+     Snapshots have two main uses:
+     * Failure recovery
+     * Migrating from one cluster to another
+
+* Use the serial (Oxford) comma. For example, “issues, bug fixes, and features”, not “issues, bug fixes and features”.
+* Don’t use the ampersand (&).
+* Avoid Latinisms, such as _e.g._, _i.e._, or _etc._ Instead of _e.g._, use _for example_ or _such as_. Instead of _i.e._, use _that is_ or _specifically_. Generally speaking, _etc._ and its equivalents (such as _and more_ or _and so on_) aren’t necessary.
+
+## Special considerations for blog posts
+
+Blog posts provide an informal approach to educating or inspiring readers through the personal perspective of the authors. Brief posts generally accompany service or feature releases, and longer posts may note best practices or provide creative solutions. Each post must provide a clear community benefit.
+
+To enhance the strengths of the blogging platform, follow these post guidelines:
+
+**Be conversational and informal.**
+
+Posts tend to be more personable, unlike technical documentation. Ask questions, include relevant anecdotes, add recommendations, and generally try to make the post as approachable as possible. However, be careful of slang, jargon, and phrases that a global audience might not understand.
+
+**Keep it short.**
+
+Deep topics don’t necessarily require long posts. Shorter, more focused posts are easier for readers to digest. Consider breaking a long post into a series, which can also encourage repeat visitors to the blog channel.
+
+**Avoid redundancy.**
+
+Posts should add to the conversation. Instead of repeating content that is already available elsewhere, link to detail pages and technical documentation. Keep only the information that is specific to the post solution or recommendations.
+
+**Connect with other content.**
+
+All posts should contain one or more calls to action that give readers the opportunity to create resources, learn more about services or features, or connect with other community members. Posts should also include metadata tags such as services, solutions, or learning levels to help readers navigate to related content.
+
+## Inclusive content
+
+When developing OpenSearch Project documentation, we strive to create content that is inclusive and free of bias. We use inclusive language to connect with the diverse and global OpenSearch Project audience, and we are careful in our word choices. Inclusive and bias-free content improves clarity and accessibility of our content for all audiences, so we avoid ableist and sexist language and language that perpetuates racist structures or stereotypes. In practical terms, this means that we do not allow certain terms to appear in our content, and we avoid using others, *depending on the context*.
+
+Our philosophy is that we positively impact users and our industry as we proactively reduce our use of terms that are problematic in some contexts. Instead, we use more technically precise language and terms that are inclusive of all audiences.
+
+### Offensive terms
+
+The following terms may be associated with unconscious racial bias, violence, or politically sensitive topics and should not appear in OpenSearch Project content, if possible. Note that many of these terms are still present but on a path to not being supported. For example, `slave` was removed from the Python programming language in 2018, and the open-source community continues to work toward replacing these terms.
+
+| Don’t use      | Guidance/Use instead        |
+|----------------|-----------------------------|
+| abort          | Don't use because it has unpleasant associations and is unnecessarily harsh sounding. Use *stop*, *end*, or *cancel* instead.                    |
+| black day      | blocked day                 |
+| blacklist      | deny list                   |
+| kill           | Don't use. Replace with *stop*, *end*, *clear*, *remove*, or *cancel*. <br><br> Exception: *Kill* is unavoidable when referring to Linux kill commands. |
+| master         | primary, main, leader       |

+| white day      | open day                    |
+| whitelist      | allow list                  |
+
+### Sensitive terms
+
+The following terms may be problematic *in some contexts*. This doesn’t mean that you can’t use these terms—just be mindful of their potential associations when using them, and avoid using them to refer to people. 
+
+| Avoid using              | Guidance/Use instead                |

+| demilitarized zone (DMZ) | perimeter network, perimeter zone   |
+
+## Trademark policy
+
+The “OpenSearch” word mark should be used in its exact form and not abbreviated or combined with any other word or words (e.g., “OpenSearch” software rather than “OPNSRCH” or “OpenSearch-ified”). See the [OpenSearch Trademark Policy](https://opensearch.org/trademark-usage.html) for more information. Also refer to the policy and to the [OpenSearch Brand Guidelines](https://opensearch.org/brand.html) for guidance regarding the use of the OpenSearch logo.

+Use only for physical space or screen descriptions, for example, "the outlet above the floor" or "the button above the bar pane."
+
+For orientation within a document use *previous*, *preceding*, or *earlier*.
+
+**ad hoc**
+
+Avoid. Use *one-time* instead.
+
+**affect**

+
+**Alerting**
+
+A plugin that notifies you when data from one or more OpenSearch indexes meets certain conditions.
+
+**allow**
+
+Use allow when the user must have security permissions in order to complete the task.
+
+Avoid using allow to refer to making something possible for the user. Instead, rewrite to focus on what’s important from the user’s point of view.
+
+**allow list**
+
+Use to describe a list of items that are allowed (not blocked). Do not use as a verb. Do not use whitelist.
+
+**Amazon OpenSearch Service**
+
+Amazon OpenSearch Service is a managed service that makes it easy to deploy, operate, and scale OpenSearch clusters in the AWS Cloud. Amazon OpenSearch Service is the successor to Amazon Elasticsearch Service (Amazon ES) and supports OpenSearch and legacy Elasticsearch OSS (up to 7.10, the final open-source version of the software).
+
+**Anomaly Detection**
+
+A plugin that automatically detects anomalies in your OpenSearch data in near real time.

+
+**auto scaling**
+
+Lower case scaling, auto scaling, and automatic scaling (but not autoscaling) are the preferred descriptive terms when generically describing auto scaling functionality.
+
+Do not use hyphenated auto-scaling as a compound modifier. Instead, use scaling (for example, scaling policy), or scalable (for example, scalable target or scalable, load-balanced environment).

+Use on first appearance. On subsequent appearances, *Signature Version 4* may be used. Only use *SigV4* when space is limited.
+
+## B
+
+**below**
+
+Use only for physical space or screen descriptions, such as “the outlet below the vent,” or “the button below the bar pane.”
+
+For orientation within a document, use *following* or *later*.
+
+**big data**
+
+**black day**
+
+Do not use. Use *blocked day* instead.
+
+**blacklist**
+
+Do not use. Use *deny list* instead.
+
+**blackout**
+
+Avoid using. Use *service outage* or *blocked* instead.
+
+**BM25**
+
+A ranking function used to estimate the relevance of documents to a given search query. BM25 extends [TF–IDF](#t) by normalizing document length.
+
+**Boolean**
+
+Avoid using the name of a Boolean value at the beginning of a sentence or sentence fragment. In general, capitalize the word Boolean. For specific programming languages, follow the usage in that language.
+
+OpenSearch style:
+
+- You can use the Boolean functions with Boolean expressions or integer expressions.
+- IsTruncated(): A Boolean value that specifies whether the resolved target list is truncated.
+
+**bottom**
+
+Use only as a general screen reference, such as “scroll to the bottom of the page.” Don’t use for window, page, or pane references to features or controls. Rather, use *lower* instead. For example, you can use the following wording: “Choose the button on the lower left.”
+
+**browse**
+
+Use when referring to scanning information or browsing the web. Don’t use when describing how to navigate to a particular item on our site or a computer. Instead, use *see* or *navigate to*.
+
+**build (n., v.)**
+
+Use as a verb to refer to compiling and linking code. Use as a noun only to refer to a compiled version of a program (for example, *Use the current build of Amazon Linux 2*...) in a programming reference.
+
+## C
+
+**CA**
+
+certificate authority
+
+**certs, certificates**
+
+Use _certificates_ on first mention. It’s OK to use _certs_ thereafter.
+
+**checkbox, checkboxes**
+
+**CI/CD**
+
+Use _continuous integration_ and _continuous delivery (CI/CD)_ or _continuous integration and delivery (CI/CD)_ on first mention.
+
+**CLI**
+
+No need to define as _command-line interface (CLI)_.
+
+**cluster**
+
+A collection of one or more nodes.
+
+**cluster manager**
+
+A single node that routes requests for the cluster and makes changes to other nodes. Each cluster contains a single cluster manager.
+
+**command line, command-line**
+
+Two words as a noun. Hyphenate as an adjective.
+
+**console**
+
+A tool inside OpenSearch Dashboards used to interact with the OpenSearch REST API.
+
+**Cross-Cluster Replication**
+
+A plugin that replicates indexes, mappings, and metadata from one OpenSearch cluster to another. Follows an active-passive model where the follower index pulls data from a leader index.
+
+**cyber**
+
+Except when dictated by open standards, use as a prefix in a closed compound: don’t use spaces or hyphens between _cyber_ and the rest of the word.
+
+## D
+
+**data**
+
+Use data is, not data are. Don’t use datas. Use pieces of data or equivalent to describe individual items within a set of data.
+
+**data center**
+
+**dataset**
+
+**data source**
+
+**data store, datastore**
+
+Two words when used generically, but one word when referring to the VMware product.
+
+**data type**
+
+**dates**
+
+Use one of the following date formats:
+
+- When a human-readable date format is preferred, spell out the date using the Month D, YYYY format (for example, _October 1, 2022_). Do not use an ordinal number for the day (use _1_, not _1st_). If the context is clear, you can omit the year on subsequent mention. If the specific day isn’t known, use the Month YYYY format (for example, _October 2022_).
+- When a numeric, lexicographically sortable date is required, use the YYYY-MM-DD format (for example, _2022-10-01_). Make sure to add a zero (0) in front of a single-digit month and day. This is the ISO 8601 standard date format. Make sure also that you use a hyphen (-) and avoid omitting the year. Doing so avoids the ambiguity that’s caused by the common, locally used formats of MM/DD and DD/MM.
+
+**demilitarized zone (DMZ)**
+
+Avoid using. Use *perimeter network* or *perimeter zone* instead.
+
+**deny list**
+
+Use to describe a list of items that aren’t allowed (blocked). Do not use _blacklist_.
+
+**disable**
+
+Use *disable* to describe making a feature or command unavailable. For example:
+
+- Clear the checkbox to disable automatic monitoring.
+- The feature is disabled by default.
+
+Note that alternatives to *disable*—such as *deactivate*, *turn off*, or *stop*—are acceptable usage where appropriate and may be found in existing documentation. In all cases, use language that corresponds to the language used in the UI, if applicable.
+
+Do not use *disable* to refer to users.
+
+**double-click**
+
+Always hyphenated. Don’t use _double click_.
+
+**dropdown list**
+
+**due to**
+
+Don’t use. Use _because of_ instead.
+
+## E
+
+**easy, easier, easily**
+
+Avoid the use of *easy*, *easier*, or *easily* if possible when describing or comparing an OpenSearch Project product, feature, or procedure in technical content. Use of these terms is audience dependent. These terms are potentially misleading or inaccurate and might be perceived as condescending by some technical users. Instead, describe what the user can do.
+
+On documentation landing pages, it’s acceptable to use *easy*, *easier*, or *easily* within the service description only.
+
+**effect**
+
+_Effect_ as a noun refers to something that’s caused by something else. _Effect_ as a verb means to bring about. Do not confuse with _affect_.
+
+**e.g.**
+
+Avoid. Use _for example_ or _such as_ instead.
+
+**Elastic IP address**
+
+**email**
+
+Use as a singular noun or adjective to refer to the collective concept, and use _message_ or _mail_ for individual items. Use _send email_ as the verb form. Don’t use the plural form because it’s a collective noun.
+
+**enable**
+
+Use *enable* to describe making a feature or command available. For example:
+
+- Select the checkbox to enable automatic monitoring.
+- The feature is enabled by default.
+
+Note that alternatives to *enable*—such as *activate*, *turn on*, or *start*—are acceptable usage where appropriate and may be found in existing documentation. In all cases, use language that corresponds to the language used in the UI, if applicable.
+
+Avoid using *enable* to refer to making something possible for the user. Instead, rewrite to focus on what's important from the user's point of view. For example, “With ABC, you can do XYZ” is a stronger statement than “ABC enables you to XYZ.” Additionally, using a task-based statement is usually more clear than the vague “…enables you to….”
+
+**enter**
+
+In general, use in preference to _type_ when a user adds text or other input (such as numbers or symbols).
+
+**etc., et cetera**
+
+Do not use.
+
+Generally speaking, etc. and its equivalents (such as and more or and so on) aren’t necessary.
+
+**execute**
+
+Replace with a more specific verb. In the sense of carrying out an action, use *run*, *process*, or *apply*. In the sense of initiating an operation, use *start*, *launch*, or *initiate*.
+
+Exception: *Execution* is unavoidable for third-party terms for which no alternative was determined, such as SQL execution plans. *Executable* is also unavoidable.
+
+## F 
+
+**fail over (v.), failover (n.)**
+
+**Faiss**
+
+**file name**
+
+**frontend (n., adj.)**
+
+Use frontend as an adjective and a noun. Do not use front end or front-end. Do not make frontend possessive except as part of a compound noun, such as frontend system.
+
+## G
+
+**generative AI**
+
+Do not use _GenAI_, _Gen AI_, _gen AI_, or _genAI_. To avoid the overuse of *generative AI*, *AI/ML-powered applications* may also be used.
+
+**geodistance**
+
+**geohash**
+
+**geohex**
+
+**geopoint**
+
+**geopolygon**
+
+**geoshape**
+
+**geospatial**
+
+**geotile**
+ 
+## H
+
+**hang**
+
+Do not use. This term is unnecessarily violent for technical documentation. Use *stop responding* instead.
+
+**hardcode**
+
+**hard disk drive (HDD)**
+
+**high availability (HA)**
+
+**high performance computing (HPC)**
+
+**hostname**
+
+**Hugging Face**
+
+## I
+
+**i.e.**
+
+Do not use. Use _that_ is or _specifically_ instead.
+
+**if, whether**
+
+Do not use *if* to mean *whether*. It is best to use *whether* in reference to a choice or alternatives ("we're going whether it rains or not") and *if* when establishing a condition ("we will go if it doesn't rain").
+
+**in, on**
+
+Use _in Windows_ or _in Linux_ in reference to components of the OS or work in the OS. Use on Windows in reference to Windows applications. Examples:
+
+- Use the Devices and Printers Control Panel in Windows to install a new printer.
+- In Windows, run the setup command.
+- Select an application that runs on Windows.
+
+Run applications and instances _in the cloud_, but extend services to the cloud.
+
+Use *on the forum*. Whatever is on the internet (the various websites, etc.), you are *on* because you cannot be *in* it.
+
+**index, indexes**
+
+In technical documentation and the UI, use *indexes* as the plural form of *index*. Use *indices* only in the context of mathematical expressions. Variable and setting names should not be changed.
+
+In blog posts, use the plural *indexes* unless there is a domain-specific reason (for example, a mathematical or financial context) to use *indices*.
+
+**Index Management (IM)**
+
+**Index State Management (ISM)**
+
+**ingest pipeline**
+
+Not _ingestion pipeline_.
+
+**inline**
+
+**install in, on**
+
+install in a folder, directory, or path; install on a disk, drive, or instance.
+
+**internet**
+
+Do not capitalize.
+

+Avoid using. Use *not valid* instead.
+
+**IP address**
+
+Don’t abbreviate as _IP only_.
+
+## J
+
+**just**
+
+Use *just* in the sense of *just now* (as in "the resources that you just created"). Otherwise, use *only* in all other contexts (to mean "limited to; nothing more than").
+
+## K
+
+**keystore**
+
+**key-value**
+
+Not _key/value_.
+
+**kill**
+
+Do not use. Replace with *stop*, *end*, *clear*, *remove*, or *cancel*.
+
+Exception: *Kill* is unavoidable when referring to Linux kill commands.
+
+**k-means**
+
+A simple and popular unsupervised clustering ML algorithm built on top of Tribuo library that chooses random centroids and calculates iteratively to optimize the position of the centroids until each observation belongs to the cluster with the nearest mean.
+
+**k-NN**
+
+Short for _k-nearest neighbors_, the k-NN plugin enables users to search for the k-nearest neighbors to a query point across an index of vectors. No need to define.
+
+## L
+
+**launch, start**
+
+You _start_ an application but _launch_ an instance, environment, or cluster.
+
+**let**
+
+Avoid using _let_ to refer to making something in a service or feature possible for the user. Instead, rewrite to focus on what’s important from the user’s point of view.
+
+**leverage**
+
+Replace with _use_.
+
+**lifecycle**
+
+One word in reference to software.
+
+**like (prep.)**
+
+OK to use to call out something for comparison.
+
+As a general rule, if you can replace like with similar to, it’s OK to use like. But, if you can replace _like_ with _such as_, use _such as_.
+
+**LLM**
+
+Define on first appearance as _large language model (LLM)_.
+
+**locate in, on**
+
+Located _in_ (a folder, directory, path), located on a disk drive or instance.
+
+**log in (v.), login (adj., n.)**
+
+Use with technologies with interfaces that use this verb. Also note that you log in to an instance, not log into. Also use log out and logout.
+
+**Logstash**
+
+A light-weight, open-source, server-side data processing pipeline that allows you to collect data from a variety of sources, transform it on the fly, and send it to your desired destination.
+
+**lower left, lower right**

+Hyphenate as adjectives. Use instead of *bottom left* and *bottom right*, unless the field name uses *bottom*. For example, "The lower-right corner."
+
+**LTS**
+
+Long-Term Support
+
+**Lucene**
+
+Apache Lucene™ is a high-performance, full-featured search engine library written entirely in Java. OpenSearch uses a modified version of Lucene as the basis for search operations within OpenSearch.
+
+## M 
+
+**machine learning**
+
+When *machine learning* is used multiple times in a document, use *machine learning (ML)* on first mention and *ML* thereafter. There is no need to redefine *ML* when *AI/ML* has already been defined. If spelled out, write *machine learning* as two words (no hyphen) in all cases, including when used as an adjective before a noun.
+
+**Machine Learning (ML) Commons**
+
+A new plugin that makes it easy to develop new ML features. It allows engineers to leverage existing open-source ML algorithms and reduce the efforts to build them from scratch.
+
+**master**
+
+Do not use. Use *primary*, *main*, or *leader* instead.
+
+**master account**
+
+Do not use. Use *management account* instead.
+
+**may**
+
+Avoid. Use _can_ or _might_ instead.
+
+**multilayer, multilayered**
+
+**must, shall, should**
+
+_Must_ and _shall_ refer to requirements. If the reader doesn’t follow the instruction, something won’t work right.
+
+_Should_ is used with recommendations. If the reader doesn’t follow the instruction, it might be harder or slower, but it’ll work.
+
+## N 
+
+**navigate to**
+
+Not navigate _in_.
+
+**near real time (n.), near real-time (adj.) (NRT)**
+
+Use _near real time_ as a noun; use near real-time as an adjective. Don’t add a hyphen between _near_ and _real time_ or _real-time_.
+
+Spell out _near real time_ on first mention; _NRT_ can be used on subsequent mentions.
+
+**node**
+
+A server that stores your data and processes search requests with OpenSearch, usually as part of a cluster. Do not use _master node_ and avoid using _worker node_.
+
+**non-production**
+
+Hyphenate to make the term easier to scan and read.
+
+## O
+
+**onsite**
+
+**OpenSearch**
+
+OpenSearch is a community-driven, open-source search and analytics suite derived from Apache 2.0 licensed Elasticsearch 7.10.2 and Kibana 7.10.2. It consists of a search engine daemon, OpenSearch, and a visualization and user interface, OpenSearch Dashboards.
+
+**OpenSearch Dashboards**
+
+The default visualization tool for data in OpenSearch. On first appearance, use the full name. *Dashboards* may be used on subsequent appearances.
+
+open source (n.), open-source (adj.)
+
+Use _open source_ as a noun (for example, “The code used throughout this tutorial is open source and can be freely modified”). Use _open-source_ as an adjective _(open-source software)_.

+Do not precede with _the_. OpenSearch Playground provides a central location for existing and evaluating users to explore features in OpenSearch and OpenSearch Dashboards without downloading or installing any OpenSearch components locally.
+
+**operating system**
+
+When referencing operating systems in documentation, follow these guidelines:
+
+- In general, if your docs or procedures apply to both Linux and macOS, you can also include Unix.
+- Unix and UNIX aren’t the same. UNIX is a trademarked name that’s owned by The Open Group. In most cases, you should use Unix.
+- When referring to the Mac operating system, use macOS. Don’t say Mac, Mac OS, or OS X.
+- When referring to Windows, it’s not necessary to prefix with Microsoft.
+- If you need to reference multiple Unix-like operating systems, you should separate by commas and use the following order: Linux, macOS, or Unix.
+
+**or earlier, or later**
+
+OK to use with software versions.
+
+## P 
+
+**Painless**
+
+The default scripting language for OpenSearch, either used inline or stored for repeat use. Similar to Java’s language specification.

+     - queries per second (QPS)
+     - bits per second (bps)
+     - megabytes per second (MBps)
+- Consider writing around _per_ elsewhere. _Per_ can sound stuffy and confusing to some global users.

+
+**query**
+
+A call used to request information about your data.
+
+## R 
+
+**real time (n.) real-time (adj.)**
+
+Use with caution; this term can imply a degree of responsiveness or speed that may not be true. When needed, use _real time_ as a noun (for example “The request is sent in real time”). Use _real-time_ as an adjective (“A real-time feed is displayed...”).
+
+**recall**
+
+The quantity of documents returned from a query.
+
+**replica shard**
+
+Copy of a primary shard. Helps improve performance when using indexes across multiple nodes.
+
+**repo**

+Avoid using. Use *separate* or *isolate* instead.
+
+**setting**
+
+A key-value pair that creates a mapping in one of the many YAML configuration files used throughout OpenSearch. Sometimes alternatively called parameters, the programming language manipulating the key-value pair usually dictates the name of this mapping in a YAML file. For OpenSearch documentation (Java), they are properly a `Setting` object.
+
+The following examples of settings illustrate key-value pairs with a colon separating the two elements:
+
+`Settings.index.number_of_shards: 4`
+
+`plugins.security.audit.enable_rest: true`
+
+**set up (v.), setup (n., adj.)**
+
+Use _set up_ as a verb (“To set up a new user...”). Use _setup_ as a noun or adjective (“To begin setup...”).
+
+**shard**
+
+A piece of an index that consumes CPU and memory. Operates as a full Lucene index.
+
+**simple, simply**
+
+Don't use. Both *simple* and *simply* are not neutral in tone and might sound condescending to some users. If you mean *only*, use *only* instead.
+
+**since**
+
+Use only to describe time events. Don’t use in place of because.
+
+**slave**
+
+Do not use. Use *replica*, *secondary*, or *standby* instead.

+
+**start, launch**
+
+You _start_ an application but _launch_ an instance, environment, or cluster.
+
+**startup (n.), start up (v.)**
+
+Never hyphenated. Use _startup_ as a noun (for example, “The following startup procedure guides you through...”). Use _start up_ as a verb (“You can start up the instances by...”).
+
+**Stochastic Gradient Descent (SGD)**
+
+## T
+
+**term frequency–inverse document frequency (TF–IDF)**
+
+A numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.
+
+**time out (verb), timeout (noun, adjective)**
+
+Never hyphenate. Use _time out_ as a verb (“The request will time out if the server doesn’t respond”). Use _timeout_ as a noun or adjective (“You can set the timeout interval by entering a number into...”).
+
+**time frame**
+
+**time-series data**
+
+Data that's provided as part of a metric. The time value is assumed to be when the value occurred.
+
+**timestamp**
+
+**time zone**
+
+**trade-off**
+
+**trigger**
+
+Avoid using as a verb to refer to an action that precipitates a subsequent action. It is OK to use when referring to a feature name, such as a *trigger function* or *time-triggered architecture*. As a verb, use an alternative, such as *initiate*, *invoke*, *launch*, or *start*.
+
+**truststore**
+
+**turn on, turn off**
+
+Use *turn on* and *turn off* in reference to a toggle to describe switching a setting or mode on or off.
+
+Don't use *choose*, *select*, *clear*, *slide*, *enable*, or *disable* for a toggle.
+
+For making a feature available or unavailable, use *enable*.
+
+## U 
+
+**UltraWarm**
+
+A storage tier that you can use to store and analyze your data with Elasticsearch and Kibana that is optimized for performance. To learn more about the service, see the introductory [blog post](https://aws.amazon.com/about-aws/whats-new/2020/05/aws-announces-amazon-elasticsearch-service-ultrawarm-general-availability/).
+
+**upper left, upper right**
+
+Hyphenate as adjectives. Use instead of *top left* and *top right*, unless the field name uses *top*. For example, "The upper-right corner."
+
+**US**
+
+No periods, as specified in the Chicago Manual of Style.
+
+**user**
+
+In most cases, replace with the more direct form you. Reserve _user_ for cases where you are referring to a third party (not the audience you are writing for).
+
+**username**
+
+## V
+
+**version**
+
+**v., vs., versus**
+
+Do not use. Use _compared_ to or _compared with_ instead.

+
+**webpage**
+
+Never _web page_.
+
+**website**
+
+Never _web site_.
+
+**while, although, whereas**
+
+Only use _while_ to mean “during an interval of time.” Don’t use it to mean although because it is often ambiguous. _Whereas_ is a better alternative to although in many cases, but it can sound overly formal.
+
+**white day**
+
+Do not use. Use *open day* instead.
+
+**whitelist**
+
+Do not use. Use *allow list* instead.
+
+**white space**
+
+**wish, want, desire, need**
+
+_Wish_ and _desire_ are indirect and nuanced versions of _want_. Don’t use them. Be direct.
+
+Do not confuse wants with needs. Use the term that’s appropriate to the situation. _Need_ connotes a requirement or obligation, whereas _want_ indicates that you have an intent but still a choice of valid actions.
+
+## Y 
+
+**Yellowdog Updater Modified (YUM)**
+
+An open-source tool for command-line and graphical-based package management for RPM (RedHat Package Manager)-based Linux systems.

+## 1.x
+
+### Migrating to OpenSearch and limits on the number of nested JSON objects
+
+Migrating from Elasticsearch OSS version 6.8 to OpenSearch version 1.x will fail when a cluster contains any document that includes more than 10,000 nested JSON objects across all fields. Elasticsearch version 7.0 introduced the `index.mapping.nested_objects.limit` setting to guard against out-of-memory errors and assigned the setting a default of `10000`. OpenSearch adopted this setting at its inception and enforces the limitation on nested JSON objects. However, because the setting is not present in Elasticsearch 6.8 and not recognized by this version, migration to OpenSearch 1.x can result in incompatibility issues that block shard relocation between Elasticsearch 6.8 and OpenSearch versions 1.x when the number of nested JSON objects in any document surpasses the default limit. 
+
+Therefore, we recommend evaluating your data for these limits before attempting to migrate from Elasticsearch 6.8.
+
+
+## 2.0.0
+
+### Remove mapping types parameter
+
+The `type` parameter has been removed from all OpenSearch API endpoints. Instead, indexes can be categorized by document type. For more details, see issue [#1940](https://github.com/opensearch-project/opensearch/issues/1940).
+
+### Deprecate non-inclusive terms 
+
+Non-inclusive terms are deprecated in version 2.x and will be permanently removed in OpenSearch 3.0.  We are using the following replacements: 
+
+- "Whitelist" is now "Allow list"
+- "Blacklist" is now "Deny list"
+- "Master" is now "Cluster Manager"
+
+### Add OpenSearch Notifications plugins
+
+In OpenSearch 2.0, the Alerting plugin is now integrated with new plugins for Notifications. If you want to continue to use the notification action in the Alerting plugin, install the new backend plugins `notifications-core` and `notifications`. If you want to manage notifications in OpenSearch Dashboards, use the new `notificationsDashboards` plugin. For more information, see [Notifications]({{site.url}}{{site.baseurl}}/observing-your-data/notifications/index/) on the OpenSearch documentation page.
+
+### Drop support for JDK 8
+
+A Lucene upgrade forced OpenSearch to drop support for JDK 8. As a consequence, the [Java high-level REST client]({{site.url}}{{site.baseurl}}/clients/java-rest-high-level/) no longer supports JDK 8. Restoring JDK 8 support is currently an `opensearch-java` proposal [#156](https://github.com/opensearch-project/opensearch-java/issues/156) and will require removing OpenSearch core as a dependency from the Java client (issue [#262](https://github.com/opensearch-project/opensearch-java/issues/262)).
+
+
+## 2.5.0
+
+### Wildcard query behavior for text fields
+
+OpenSearch 2.5 contains a bug fix to correct the behavior of the `case_insensitive` parameter for the `wildcard` query on text fields. As a result, a wildcard query on text fields that ignored case sensitivity and erroneously returned results prior to the bug fix will not return the same results. For more information, see issue [#8711](https://github.com/opensearch-project/OpenSearch/issues/8711).

+
+# Introduction to OpenSearch
+
+OpenSearch is a distributed search and analytics engine based on [Apache Lucene](https://lucene.apache.org/). After adding your data to OpenSearch, you can perform full-text searches on it with all of the features you might expect: search by field, search multiple indexes, boost fields, rank results by score, sort results by field, and aggregate results.
+
+Unsurprisingly, people often use search engines like OpenSearch as the backend for a search application---think [Wikipedia](https://en.wikipedia.org/wiki/Wikipedia:FAQ/Technical#What_software_is_used_to_run_Wikipedia?) or an online store. It offers excellent performance and can scale up and down as the needs of the application grow or shrink.
+
+An equally popular, but less obvious use case is log analytics, in which you take the logs from an application, feed them into OpenSearch, and use the rich search and visualization functionality to identify issues. For example, a malfunctioning web server might throw a 500 error 0.5% of the time, which can be hard to notice unless you have a real-time graph of all HTTP status codes that the server has thrown in the past four hours. You can use [OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/index/) to build these sorts of visualizations from data in OpenSearch.
+
+
+## Clusters and nodes
+
+Its distributed design means that you interact with OpenSearch *clusters*. Each cluster is a collection of one or more *nodes*, servers that store your data and process search requests.
+
+You can run OpenSearch locally on a laptop---its system requirements are minimal---but you can also scale a single cluster to hundreds of powerful machines in a data center.
+
+In a single node cluster, such as a laptop, one machine has to do everything: manage the state of the cluster, index and search data, and perform any preprocessing of data prior to indexing it. As a cluster grows, however, you can subdivide responsibilities. Nodes with fast disks and plenty of RAM might be great at indexing and searching data, whereas a node with plenty of CPU power and a tiny disk could manage cluster state. For more information on setting node types, see [Cluster formation]({{site.url}}{{site.baseurl}}/opensearch/cluster/).
+
+
+## Indexes and documents
+
+OpenSearch organizes data into *indexes*. Each index is a collection of JSON *documents*. If you have a set of raw encyclopedia articles or log lines that you want to add to OpenSearch, you must first convert them to [JSON](https://www.json.org/). A simple JSON document for a movie might look like this:
+
+```json
+{
+  "title": "The Wind Rises",
+  "release_date": "2013-07-20"
+}
+```
+
+When you add the document to an index, OpenSearch adds some metadata, such as the unique document *ID*:
+
+```json
+{
+  "_index": "<index-name>",
+  "_type": "_doc",
+  "_id": "<document-id>",
+  "_version": 1,
+  "_source": {
+    "title": "The Wind Rises",
+    "release_date": "2013-07-20"
+  }
+}
+```
+
+Indexes also contain mappings and settings:
+
+- A *mapping* is the collection of *fields* that documents in the index have. In this case, those fields are `title` and `release_date`.
+- Settings include data like the index name, creation date, and number of shards.
+
+## Primary and replica shards
+
+OpenSearch splits indexes into *shards* for even distribution across nodes in a cluster. For example, a 400 GB index might be too large for any single node in your cluster to handle, but split into ten shards, each one 40 GB, OpenSearch can distribute the shards across ten nodes and work with each shard individually.
+
+By default, OpenSearch creates a *replica* shard for each *primary* shard. If you split your index into ten shards, for example, OpenSearch also creates ten replica shards. These replica shards act as backups in the event of a node failure---OpenSearch distributes replica shards to different nodes than their corresponding primary shards---but they also improve the speed and rate at which the cluster can process search requests. You might specify more than one replica per index for a search-heavy workload.
+
+Despite being a piece of an OpenSearch index, each shard is actually a full Lucene index---confusing, we know. This detail is important, though, because each instance of Lucene is a running process that consumes CPU and memory. More shards is not necessarily better. Splitting a 400 GB index into 1,000 shards, for example, would place needless strain on your cluster. A good rule of thumb is to keep shard size between 10--50 GB.
+
+
+## REST API
+
+You interact with OpenSearch clusters using the REST API, which offers a lot of flexibility. You can use clients like [curl](https://curl.se/) or any programming language that can send HTTP requests. To add a JSON document to an OpenSearch index (i.e. index a document), you send an HTTP request:
+
+```json
+PUT https://<host>:<port>/<index-name>/_doc/<document-id>
+{
+  "title": "The Wind Rises",
+  "release_date": "2013-07-20"
+}
+```
+
+To run a search for the document:
+
+```json
+GET https://<host>:<port>/<index-name>/_search?q=wind
+```
+
+To delete the document:
+
+```json
+DELETE https://<host>:<port>/<index-name>/_doc/<document-id>
+```
+
+You can change most OpenSearch settings using the REST API, modify indexes, check the health of the cluster, get statistics---almost everything.
+
+## Advanced concepts
+
+The following section describes more advanced OpenSearch concepts.
+
+### Translog
+
+Any index changes, such as document indexing or deletion, are written to disk during a Lucene commit. However, Lucene commits are expensive operations, so they cannot be performed after every change to the index. Instead, each shard records every indexing operation in a transaction log called _translog_. When a document is indexed, it is added to the memory buffer and recorded in the translog. After a process or host restart, any data in the in-memory buffer is lost. Recording the document in the translog ensures durability because the translog is written to disk.
+
+Frequent refresh operations write the documents in the memory buffer to a segment and then clear the memory buffer. Periodically, a [flush](#flush) performs a Lucene commit, which includes writing the segments to disk using `fsync`, purging the old translog, and starting a new translog. Thus, a translog contains all operations that have not yet been flushed.
+
+### Refresh
+
+Periodically, OpenSearch performs a _refresh_ operation, which writes the documents from the in-memory Lucene index to files. These files are not guaranteed to be durable because an `fsync` is not performed. A refresh makes documents available for search.
+
+### Flush
+
+A _flush_ operation persists the files to disk using `fsync`, ensuring durability. Flushing ensures that the data stored only in the translog is recorded in the Lucene index. OpenSearch performs a flush as needed to ensure that the translog does not grow too large.
+
+### Merge
+
+In OpenSearch, a shard is a Lucene index, which consists of _segments_ (or segment files). Segments store the indexed data and are immutable. Periodically, smaller segments are merged into larger ones. Merging reduces the overall number of segments on each shard, frees up disk space, and improves search performance. Eventually, segments reach a maximum size specified in the merge policy and are no longer merged into larger segments. The merge policy also specifies how often merges are performed.

+
+# Quickstart
+
+Get started using OpenSearch and OpenSearch Dashboards by deploying your containers with [Docker](https://www.docker.com/). Before proceeding, you need to [get Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://github.com/docker/compose) installed on your local machine. 
+
+The Docker Compose commands used in this guide are written with a hyphen (for example, `docker-compose`). If you installed Docker Desktop on your machine, which automatically installs a bundled version of Docker Compose, then you should remove the hyphen. For example, change `docker-compose` to `docker compose`.
+{: .note}
+
+## Starting your cluster
+
+You'll need a special file, called a Compose file, that Docker Compose uses to define and create the containers in your cluster. The OpenSearch Project provides a sample Compose file that you can use to get started. Learn more about working with Compose files by reviewing the official [Compose specification](https://docs.docker.com/compose/compose-file/).
+
+1. Before running OpenSearch on your machine, you should disable memory paging and swapping performance on the host to improve performance and increase the number of memory maps available to OpenSearch. See [important system settings]({{site.url}}{{site.baseurl}}/opensearch/install/important-settings/) for more information.
+    ```bash
+    # Disable memory paging and swapping.
+    sudo swapoff -a
+
+    # Edit the sysctl config file that defines the host's max map count.
+    sudo vi /etc/sysctl.conf
+
+    # Set max map count to the recommended value of 262144.
+    vm.max_map_count=262144
+
+    # Reload the kernel parameters.
+    sudo sysctl -p
+    ```  
+1. Download the sample Compose file to your host. You can download the file with command line utilities like `curl` and `wget`, or you can manually copy [docker-compose.yml](https://github.com/opensearch-project/documentation-website/blob/{{site.opensearch_major_minor_version}}/assets/examples/docker-compose.yml) from the OpenSearch Project documentation-website repository using a web browser.
+    ```bash
+    # Using cURL:
+    curl -O https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/docker-compose.yml
+
+    # Using wget:
+    wget https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/docker-compose.yml
+    ```
+1. In your terminal application, navigate to the directory containing the `docker-compose.yml` file you just downloaded, and run the following command to create and start the cluster as a background process.
+    ```bash
+    docker-compose up -d
+    ```
+1. Confirm that the containers are running with the command `docker-compose ps`. You should see an output like the following:
+    ```bash
+    $ docker-compose ps
+    NAME                    COMMAND                  SERVICE                 STATUS              PORTS
+    opensearch-dashboards   "./opensearch-dashbo…"   opensearch-dashboards   running             0.0.0.0:5601->5601/tcp
+    opensearch-node1        "./opensearch-docker…"   opensearch-node1        running             0.0.0.0:9200->9200/tcp, 9300/tcp, 0.0.0.0:9600->9600/tcp, 9650/tcp
+    opensearch-node2        "./opensearch-docker…"   opensearch-node2        running             9200/tcp, 9300/tcp, 9600/tcp, 9650/tcp
+    ```
+1. Query the OpenSearch REST API to verify that the service is running. You should use `-k` (also written as `--insecure`) to disable hostname checking because the default security configuration uses demo certificates. Use `-u` to pass the default username and password (`admin:<custom-admin-password>`).
+    ```bash
+    curl https://localhost:9200 -ku admin:<custom-admin-password>
+    ```
+    Sample response:
+    ```json
+    {
+        "name" : "opensearch-node1",
+        "cluster_name" : "opensearch-cluster",
+        "cluster_uuid" : "W0B8gPotTAajhMPbC9D4ww",
+        "version" : {
+            "distribution" : "opensearch",
+            "number" : "2.6.0",
+            "build_type" : "tar",
+            "build_hash" : "7203a5af21a8a009aece1474446b437a3c674db6",
+            "build_date" : "2023-02-24T18:58:37.352296474Z",
+            "build_snapshot" : false,
+            "lucene_version" : "9.5.0",
+            "minimum_wire_compatibility_version" : "7.10.0",
+            "minimum_index_compatibility_version" : "7.0.0"
+        },
+        "tagline" : "The OpenSearch Project: https://opensearch.org/"
+    }
+    ```
+1. Explore OpenSearch Dashboards by opening `http://localhost:5601/` in a web browser on the same host that is running your OpenSearch cluster. The default username is `admin` and the default password is set in your `docker-compose.yml` file in the `OPENSEARCH_INITIAL_ADMIN_PASSWORD=<custom-admin-password>` setting.
+
+## Create an index and field mappings using sample data
+
+Create an index and define field mappings using a dataset provided by the OpenSearch Project. The same fictitious e-commerce data is also used for sample visualizations in OpenSearch Dashboards. To learn more, see [Getting started with OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/index/).
+
+1. Download [ecommerce-field_mappings.json](https://github.com/opensearch-project/documentation-website/blob/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce-field_mappings.json). This file defines a [mapping]({{site.url}}{{site.baseurl}}/opensearch/mappings/) for the sample data you will use.
+    ```bash
+    # Using cURL:
+    curl -O https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce-field_mappings.json
+
+    # Using wget:
+    wget https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce-field_mappings.json
+    ```
+1. Download [ecommerce.json](https://github.com/opensearch-project/documentation-website/blob/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce.json). This file contains the index data formatted so that it can be ingested by the bulk API. To learn more, see [index data]({{site.url}}{{site.baseurl}}/opensearch/index-data/) and [Bulk]({{site.url}}{{site.baseurl}}/api-reference/document-apis/bulk/).
+    ```bash
+    # Using cURL:
+    curl -O https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce.json
+
+    # Using wget:
+    wget https://raw.githubusercontent.com/opensearch-project/documentation-website/{{site.opensearch_major_minor_version}}/assets/examples/ecommerce.json
+    ```
+1. Define the field mappings with the mapping file.
+    ```bash
+    curl -H "Content-Type: application/x-ndjson" -X PUT "https://localhost:9200/ecommerce" -ku admin:<custom-admin-password> --data-binary "@ecommerce-field_mappings.json"
+    ```
+1. Upload the index to the bulk API.
+    ```bash
+    curl -H "Content-Type: application/x-ndjson" -X PUT "https://localhost:9200/ecommerce/_bulk" -ku admin:<custom-admin-password> --data-binary "@ecommerce.json"
+    ```
+1. Query the data using the search API. The following command submits a query that will return documents where `customer_first_name` is `Sonya`.
+    ```bash
+    curl -H 'Content-Type: application/json' -X GET "https://localhost:9200/ecommerce/_search?pretty=true" -ku admin:<custom-admin-password> -d' {"query":{"match":{"customer_first_name":"Sonya"}}}'
+    ```
+    Queries submitted to the OpenSearch REST API will generally return a flat JSON by default. For a human readable response body, use the query parameter `pretty=true`. For more information about `pretty` and other useful query parameters, see [Common REST parameters]({{site.url}}{{site.baseurl}}/opensearch/common-parameters/).
+1. Access OpenSearch Dashboards by opening `http://localhost:5601/` in a web browser on the same host that is running your OpenSearch cluster. The default username is `admin` and the password is set in your `docker-compose.yml` file in the `OPENSEARCH_INITIAL_ADMIN_PASSWORD=<custom-admin-password>` setting.
+1. On the top menu bar, go to **Management > Dev Tools**.
+1. In the left pane of the console, enter the following:
+    ```json
+    GET ecommerce/_search
+    {
+        "query": {
+            "match": {
+                "customer_first_name": "Sonya"
+            }
+        }
+    }
+    ```
+1. Choose the triangle icon at the top right of the request to submit the query. You can also submit the request by pressing `Ctrl+Enter` (or `Cmd+Enter` for Mac users). To learn more about using the OpenSearch Dashboards console for submitting queries, see [Running queries in the console]({{site.url}}{{site.baseurl}}/dashboards/run-queries/).
+

+
+## Common issues
+
+Review these common issues and suggested solutions if your containers fail to start or exit unexpectedly.
+
+### Docker commands require elevated permissions
+
+Eliminate the need for running your Docker commands with `sudo` by adding your user to the `docker` user group. See Docker's [Post-installation steps for Linux](https://docs.docker.com/engine/install/linux-postinstall/) for more information.
+```bash
+sudo usermod -aG docker $USER
+```
+
+### Error message: "-bash: docker-compose: command not found"
+
+If you installed Docker Desktop, then Docker Compose is already installed on your machine. Try `docker compose` (without the hyphen) instead of `docker-compose`. See [Use Docker Compose](https://docs.docker.com/get-started/08_using_compose/).
+
+### Error message: "docker: 'compose' is not a docker command."
+
+If you installed Docker Engine, then you must install Docker Compose separately, and you will use the command `docker-compose` (with a hyphen). See [Docker Compose](https://github.com/docker/compose).
+
+### Error message: "max virtual memory areas vm.max_map_count [65530] is too low"
+
+OpenSearch will fail to start if your host's `vm.max_map_count` is too low. Review the [important system settings]({{site.url}}{{site.baseurl}}/opensearch/install/important-settings/) if you see the following errors in the service log, and set `vm.max_map_count` appropriately.
+```bash
+opensearch-node1         | ERROR: [1] bootstrap checks failed
+opensearch-node1         | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
+opensearch-node1         | ERROR: OpenSearch did not exit normally - check the logs at /usr/share/opensearch/logs/opensearch-cluster.log

+# Adjacency matrix aggregations
+
+The `adjacency_matrix` aggregation lets you define filter expressions and returns a matrix of the intersecting filters where each non-empty cell in the matrix represents a bucket. You can find how many documents fall within any combination of filters.
+
+Use the `adjacency_matrix` aggregation to discover how concepts are related by visualizing the data as graphs.
+
+For example, in the sample eCommerce dataset, to analyze how the different manufacturing companies are related:
+
+```json

+
+ ```json
+ {

+ ```
+
+- `grpA`: Products manufactured by Low Tide Media.

+# Diversified sampler
+
+The `diversified_sampler` aggregation lets you reduce the bias in the distribution of the sample pool by deduplicating documents containing the same `field`. It does so by using the `max_docs_per_value` and `field` settings, which limit the maximum number of documents collected on a shard for the provided `field`. The `max_docs_per_value` setting is an optional parameter used to determine the maximum number of documents that will be returned per `field`. The default value of this setting is `1`.
+
+Similarly to the [`sampler` aggregation]({{site.url}}{{site.baseurl}}/aggregations/bucket/sampler/), you can use the `shard_size` setting to control the maximum number of documents collected on any one shard, as shown in the following example:
+
+```json

+# Filter aggregations
+
+A `filter` aggregation is a query clause, exactly like a search query — `match` or `term` or `range`. You can use the `filter` aggregation to narrow down the entire set of documents to a specific set before creating buckets.
+
+The following example shows the `avg` aggregation running within the context of a filter. The `avg` aggregation only aggregates the documents that match the `range` query:
+
+```json

+A `filters` aggregation is the same as the `filter` aggregation, except that it lets you use multiple filter aggregations.
+While the `filter` aggregation results in a single bucket, the `filters` aggregation returns multiple buckets, one for each of the defined filters.
+
+To create a bucket for all the documents that didn't match the any of the filter queries, set the `other_bucket` property to `true`:

+# Geodistance aggregations
+
+The `geo_distance` aggregation groups documents into concentric circles based on distances from an origin `geo_point` field.
+It's the same as the `range` aggregation, except that it works on geo locations.
+
+For example, you can use the `geo_distance` aggregation to find all pizza places within 1 km of you. The search results are limited to the 1 km radius specified by you, but you can add another result found within 2 km.
+
+You can only use the `geo_distance` aggregation on fields mapped as `geo_point`.
+
+A point is a single geographical coordinate, such as your current location shown by your smart-phone. A point in OpenSearch is represented as follows:
+
+```json
+{
+  "location": {
+    "type": "point",
+    "coordinates": {
+      "lat": 83.76,
+      "lon": -81.2
+    }
+  }
+}
+```
+
+You can also specify the latitude and longitude as an array `[-81.20, 83.76]` or as a string `"83.76, -81.20"`
+
+This table lists the relevant fields of a `geo_distance` aggregation:
+
+Field | Description | Required
+:--- | :--- |:---
+`field` |  Specify the geopoint field that you want to work on. | Yes
+`origin` |  Specify the geopoint that's used to compute the distances from. | Yes
+`ranges`  |  Specify a list of ranges to collect documents based on their distance from the target point. | Yes
+`unit` |  Define the units used in the `ranges` array. The `unit` defaults to `m` (meters), but you can switch to other units like `km` (kilometers), `mi` (miles), `in` (inches), `yd` (yards), `cm` (centimeters), and `mm` (millimeters).  | No
+`distance_type` | Specify how OpenSearch calculates the distance. The default is `sloppy_arc` (faster but less accurate), but can also be set to `arc` (slower but most accurate) or `plane` (fastest but least accurate). Because of high error margins, use `plane` only for small geographic areas. | No
+
+The syntax is as follows:
+
+```json
+{
+  "aggs": {
+    "aggregation_name": {
+      "geo_distance": {
+        "field": "field_1",
+        "origin": "x, y",
+        "ranges": [
+          {
+            "to": "value_1"
+          },
+          {
+            "from": "value_2",
+            "to": "value_3"
+          },
+          {
+            "from": "value_4"
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+This example forms buckets from the following distances from a `geo-point` field:
+
+- Fewer than 10 km
+- From 10 to 20 km
+- From 20 to 50 km
+- From 50 to 100 km
+- Above 100 km
