 # Agents and ingestion tools
 
 Historically, many multiple popular agents and ingestion tools have worked with Elasticsearch OSS, such as Beats, Logstash, Fluentd, FluentBit, and OpenTelemetry. OpenSearch aims to continue to support a broad set of agents and ingestion tools, but not all have been tested or have explicitly added OpenSearch compatibility.
 
-As an intermediate solution, we are adding a [version value](https://github.com/opensearch-project/OpenSearch/issues/693) to `opensearch.yml`. This change will let you set OpenSearch 1.x clusters to report version 7.10.2 (or any other arbitrary value). By reporting 7.10.2, the cluster will be able to connect with tools that check for a particular version number.
+As an intermediate compatibility solution, OpenSearch has a setting that instructs the cluster to return version 7.10.2 rather than its actual version.
 
-For a longer term solution, we plan to create an OpenSearch output plugin for Logstash. This plugin *does not exist yet*, but we've included it in the compatibility matrices below based on its expected behavior.
+If you use clients that include a version check, such as recent versions of Logstash OSS or Filebeat OSS, enable the setting:
+
+```json
+PUT _cluster/settings
+{
+  "persistent": {
+    "compatibility": {
+      "override_main_response_version": true
+    }
+  }
+}
+```
+
+
+## Downloads
+
+You can download the OpenSearch output plugin for Logstash from [OpenSearch downloads](https://opensearch.org/downloads.html). The Logstash output plugin is compatible with OpenSearch and Elasticsearch OSS (7.10.2 or lower).
+
+These versions of Beats offer the best compatibility with OpenSearch. For more information, see the [compatibility matrices](#compatibility-matrices).

+# Java high-level REST client
+
+The Elasticsearch OSS Java high-level REST client allows you to interact with your OpenSearch clusters and indices through Java methods and data structures rather than HTTP methods and JSON.
+
+You submit requests to your cluster using request objects, which allows you to create indices, add data to documents, or complete other operations with your cluster. In return, you get back response objects that have all of the available information, such as the associated index or ID, from your cluster.
+
+## Setup
+
+To start using the Elasticsearch OSS Java high-level REST client, ensure that you have the following dependency in your project's `pom.xml` file:
+
+```
+<dependency>
+  <groupId>org.elasticsearch.client</groupId>
+  <artifactId>elasticsearch-rest-high-level-client</artifactId>
+  <version>7.10.2</version>
+</dependency>
+```
+
+You can now start your OpenSearch cluster. The 7.10.2 high-level REST client works with the 1.x versions of OpenSearch.

+# Run OpenSearch Dashboards using Helm
+
+Helm is a package manager that allows you to easily install and manage OpenSearch Dashboards in a Kubernetes cluster. You can define your OpenSearch configurations in a YAML file and use Helm to deploy your applications in a version-controlled and reproducible way.
+
+The Helm chart contains the resources described in the following table.
+
+Resource | Description
+:--- | :---
+`Chart.yaml` |  Information about the chart.
+`values.yaml` |  Default configuration values for the chart.
+`templates` |  Templates that combine with values to generate the Kubernetes manifest files.
+
+The specification in the default Helm chart supports many standard use cases and setups. You can modify the default chart to configure your desired specifications and set Transport Layer Security (TLS) and role-based access control (RBAC).
+
+For information about the default configuration, steps to configure security, and configurable parameters, see the
+[README](https://github.com/opensearch-project/opensearch-devops/blob/main/Helm/README.md).
+
+The instructions here assume you have a Kubernetes cluster with Helm preinstalled. See the [Kubernetes documentation](https://kubernetes.io/docs/setup/) for steps to configure a Kubernetes cluster and the [Helm documentation](https://helm.sh/docs/intro/install/) to install Helm.
+{: .note }
+
+## Prerequisites
+
+Before you get started, you must first use [Helm to install OpenSearch]({{site.url}}{{site.baseurl}}/opensearch/install/helm/).
+
+Make sure that you can send requests to your OpenSearch pod:
+
+```json
+$ curl -XGET https://localhost:9200 -u 'admin:admin' --insecure
+{
+  "name" : "opensearch-cluster-master-1",
+  "cluster_name" : "opensearch-cluster",
+  "cluster_uuid" : "hP2gq5bPS3SLp8Z7wXm8YQ",
+  "version" : {
+    "distribution" : "opensearch",
+    "number" : "1.0.0",
+    "build_type" : "tar",
+    "build_hash" : "34550c5b17124ddc59458ef774f6b43a086522e3",
+    "build_date" : "2021-07-02T23:22:21.383695Z",
+    "build_snapshot" : false,
+    "lucene_version" : "8.8.2",
+    "minimum_wire_compatibility_version" : "6.8.0",
+    "minimum_index_compatibility_version" : "6.0.0-beta1"
+  },
+  "tagline" : "The OpenSearch Project: https://opensearch.org/"
+}
+```
+
+## Install OpenSearch Dashboards using Helm
+
+1. Change to the `opensearch-dashboards` directory:
+
+   ```bash
+   cd opensearch-dashboards
+   ```
+
+1. Package the Helm chart:
+
+   ```bash
+   helm package .
+   ```
+
+1. Deploy OpenSearch Dashboards:
+
+   ```bash
+   helm install --generate-name opensearch-dashboards-1.0.0.tgz
+   ```
+   The output shows you the specifications instantiated from the install.
+   To customize the deployment, pass in the values that you want to override with a custom YAML file:
+
+   ```bash
+   helm install --values=customvalues.yaml opensearch-dashboards-1.0.0.tgz
+   ```
+

+# Configure TLS for OpenSearch Dashboards
+
+By default, for ease of testing and getting started, OpenSearch Dashboards runs over HTTP. To enable TLS for HTTPS, update the following settings in `opensearch_dashboards.yml`.
+
+Setting | Description
+:--- | :---
+opensearch.ssl.verificationMode | This setting is for communications between OpenSearch and OpenSearch Dashboards. Valid values are `full`, `certificate`, or `none`. We recommend `full` if you enable TLS, which enables hostname verification. `certificate` just checks the certificate, not the hostname, and `none` performs no checks (suitable for HTTP). Default is `full`.
+opensearch.ssl.certificateAuthorities | If `opensearch.ssl.verificationMode` is `full` or `certificate`, specify the full path to one or more CA certificates that comprise a trusted chain for your OpenSearch cluster. For example, you might need to include a root CA _and_ an intermediate CA if you used the intermediate CA to issue your admin, client, and node certificates.
+server.ssl.enabled | This setting is for communications between OpenSearch Dashboards and the web browser. Set to true for HTTPS, false for HTTP.
+server.ssl.certificate | If `server.ssl.enabled` is true, specify the full path to a valid client certificate for your OpenSearch cluster. You can [generate your own]({{site.url}}{{site.baseurl}}/security-plugin/configuration/generate-certificates/) or get one from a certificate authority.
+server.ssl.key | If `server.ssl.enabled` is true, specify the full path (e.g. `/usr/share/opensearch-dashboards-1.0.0/config/my-client-cert-key.pem` to the key for your client certificate. You can [generate your own]({{site.url}}{{site.baseurl}}/security-plugin/configuration/generate-certificates/) or get one from a certificate authority.
+opensearch_security.cookie.secure | If you enable TLS for OpenSearch Dashboards, change this setting to `true`. For HTTP, set it to `false`.
+
+This `opensearch_dashboards.yml` configuration shows OpenSearch and OpenSearch Dashboards running on the same machine with the demo configuration:
+
+```yml
+opensearch.hosts: ["https://localhost:9200"]
+opensearch.ssl.verificationMode: full
+opensearch.username: "kibanaserver"
+opensearch.password: "kibanaserver"
+opensearch.requestHeadersWhitelist: [ authorization,securitytenant ]
+server.ssl.enabled: true
+server.ssl.certificate: /usr/share/opensearch-dashboards/config/client-cert.pem
+server.ssl.key: /usr/share/opensearch-dashboards/config/client-cert-key.pem
+opensearch.ssl.certificateAuthorities: [ "/usr/share/opensearch-dashboards/config/root-ca.pem", "/usr/share/opensearch-dashboards/config/intermediate-ca.pem" ]
+opensearch_security.multitenancy.enabled: true
+opensearch_security.multitenancy.tenants.preferred: ["Private", "Global"]
+opensearch_security.readonly_mode.roles: ["kibana_read_only"]
+opensearch_security.cookie.secure: true
+```
+
+If you use the Docker install, you can pass a custom `opensearch_dashboards.yml` to the container. To learn more, see the [Docker installation page]({{site.url}}{{site.baseurl}}/opensearch/install/docker/).
+
+After enabling these settings and starting OpenSearch Dashboards, you can connect to it at `https://localhost:5601`. You might have to acknowledge a browser warning if your certificates are self-signed. To avoid this sort of warning (or outright browser incompatibility), best practice is to use certificates from trusted certificate authority.

 After you attach a policy to an index, ISM creates a job that runs every 5 minutes by default to perform policy actions, check conditions, and transition the index into different states. To change the default time interval for this job, see [Settings]({{site.url}}{{site.baseurl}}/im-plugin/ism/settings/).

-# Docker migration
-
-If you use a container orchestration system like Kubernetes (or manage your containers manually) and want to avoid downtime, think of the process not as an upgrade of each node, but as a decommissioning and replacement of each node. One by one, add OpenSearch nodes to the cluster and remove Elasticsearch OSS nodes, allowing time for all indices to return to a green status prior to proceeding.
-
-If you use Docker Compose, we highly recommend that you perform what amounts to a [cluster restart upgrade]({{site.url}}{{site.baseurl}}/migrate/upgrade-migrate/). Update your cluster configuration with new images, new settings, and new environment variables, and test it. Then stop and start the cluster. This process requires downtime, but takes very few steps and lets you continue to treat the cluster as a single entity that you can reliably deploy and redeploy.
-
-The most important step is to leave your data volumes intact. **Don't** run `docker-compose down -v`.

-# About migrating
-
-The process of migrating from Elasticsearch OSS (including Open Distro for Elasticsearch) to OpenSearch varies depending on your current version of Elasticsearch OSS, install type, tolerance for downtime, and cost-sensitivity. Rather than concrete steps to cover every situation, we have general guidance for the process.
-
-To safeguard against data loss, we recommend that you take a [snapshot]({{site.url}}{{site.baseurl}}/opensearch/snapshot-restore/) of all indices prior to any migration.

-# cat API
-
-You can get essential statistics about your cluster in an easy-to-understand, tabular format using the compact and aligned text (CAT) API. The cat API is a human-readable interface that returns plain text instead of traditional JSON.
-
-Using the cat API, you can answer questions like which node is the elected master, what state is the cluster in, how many documents are in each index, and so on.
-
-To see the available operations in the cat API, use the following command:
-
-```
-GET _cat
-```
-
-You can also use the following string parameters with your query.
-
-Parameter | Description
-:--- | :--- |
-`?v` |  Makes the output more verbose by adding headers to the columns. It also adds some formatting to help align each of the columns together. All examples on this page include the `v` parameter.
-`?help` | Lists the default and other available headers for a given operation.
-`?h`  |  Limits the output to specific headers.
-`?format` |  Outputs the result in JSON, YAML, or CBOR formats.
-`?sort` | Sorts the output by the specified columns.
-
-To see what each column represents, use the `?v` parameter:
-
-```
-GET _cat/<operation_name>?v
-```
-
-To see all the available headers, use the `?help` parameter:
-
-```
-GET _cat/<operation_name>?help
-```
-
-To limit the output to a subset of headers, use the `?h` parameter:
-
-```
-GET _cat/<operation_name>?h=<header_name_1>,<header_name_2>&v
-```
-
-Typically, for any operation you can find out what headers are available using the `?help` parameter, and then use the `?h` parameter to limit the output to only the headers that you care about.

+# Data streams
+
+If you're ingesting continuously generated time-series data such as logs, events, and metrics into OpenSearch, you're likely in a scenario where the number of documents grows rapidly and you don't need to update older documents.
+
+A typical workflow to manage time-series data involves multiple steps such as creating a rollover index alias, defining a write index, and defining common mappings and settings for the backing indices.
+
+Data streams simplify this bootstrapping process and enforce a setup that best suits time-series data, such as being designed primarily for append-only data, and ensuring that each document has a timestamp field.
+
+A data stream is internally composed of multiple backing indices. Search requests are routed to all the backing indices, while indexing requests are routed to the latest write index. You can use [ISM]({{site.url}}{{site.baseurl}}/im-plugin/ism/index/) policies to automatically handle rollovers or deletion of indices in a data stream, based on your use case.
+
+
+## About data streams
+
+A data stream consists of one or more hidden auto-generated backing indices. These backing indices are named using the following convention:
+
+```
+.ds-<data-stream-name>-<generation-id>
+```
+
+For example, `.ds-logs-redis-000003`, where generation-id is a six-digit, zero-padded integer that acts as a cumulative count of the data stream’s rollovers, starting at `000001`.
+
+The most recently created backing index is the data stream’s write index. You can’t add documents directly to any of the backing indices. You can only add them via the data stream handle:
+
+![data stream indexing diagram]({{site.url}}{{site.baseurl}}/images/data_stream_indexing.png)
+
+The data stream routes search requests to all of its backing indices. It uses the timestamp field to intelligently route search requests to the right set of indices and shards:
+
+![data stream indexing diagram]({{site.url}}{{site.baseurl}}/images/data_stream_searching.png)
+
+The following operations are not supported on the write index because they might hinder the indexing operation:
+
+- close
+- clone
+- delete
+- shrink
+- split
+
+## Get started with data streams
+
+### Step 1: Create an index template
+
+To create a data stream, you first need to create an index template that configures a set of indices as a data stream. The `data_stream` object indicates that it’s a data stream and not a regular index template. The index pattern matches with the name of the data stream:
+
+```json
+PUT _index_template/logs-template
+{
+  "index_patterns": [
+    "my-data-stream",
+    "logs-*"
+  ],
+  "data_stream": {},
+  "priority": 100
+}
+```
+
+In this case, each ingested document must have an `@timestamp` field.
+You also have the ability to define your own custom timestamp field as a property in the `data_stream` object. You can also add index mappings and other settings here, just as you would for a regular index template.
+
+```json
+PUT _index_template/logs-template-nginx
+{
+  "index_patterns": "logs-nginx",
+  "data_stream": {
+    "timestamp_field": {
+      "name": "request_time"
+    }
+  },
+  "priority": 200,
+  "template": {
+    "settings": {
+      "number_of_shards": 1,
+      "number_of_replicas": 0
+    }
+  }
+}
+```
+
+In this case, `logs-nginx` index matches both the `logs-template` and `logs-template-nginx` templates. When you have a tie, OpenSearch selects the matching index template with the higher priority value.
+
+### Step 2: Create a data stream
+
+After you create an index template, you can create a data stream.
+You can use the data stream API to explicitly create a data stream. The data stream API initializes the first backing index:
+
+```json
+PUT _data_stream/logs-redis
+PUT _data_stream/logs-nginx
+```
+
+You can also directly start ingesting data without creating a data stream.
+
+Because we have a matching index template with a data_stream object, OpenSearch automatically creates the data stream:
+
+```json
+POST logs-staging/_doc
+{
+  "message": "login attempt failed",
+  "@timestamp": "2013-03-01T00:00:00"
+}
+```
+
+To see information about a specific data stream:
+
+```json
+GET _data_stream/logs-nginx
+```
+
+#### Sample response
+
+```json
+{
+  "data_streams" : [
+    {
+      "name" : "logs-nginx",
+      "timestamp_field" : {
+        "name" : "request_time"
+      },
+      "indices" : [
+        {
+          "index_name" : ".ds-logs-nginx-000001",
+          "index_uuid" : "-VhmuhrQQ6ipYCmBhn6vLw"
+        }
+      ],
+      "generation" : 1,
+      "status" : "GREEN",
+      "template" : "logs-template-nginx"
+    }
+  ]
+}
+```
+
+You can see the name of the timestamp field, the list of the backing indices, and the template that's used to create the data stream. You can also see the health of the data stream, which represents the lowest status of all its backing indices.
+
+To see more insights about the data stream, use the `_stats` endpoint:
+
+```json
+GET _data_stream/logs-nginx/_stats
+```
+
+#### Sample response
+
+```json
+{
+  "_shards" : {
+    "total" : 1,
+    "successful" : 1,
+    "failed" : 0
+  },
+  "data_stream_count" : 1,
+  "backing_indices" : 1,
+  "total_store_size_bytes" : 208,
+  "data_streams" : [
+    {
+      "data_stream" : "logs-nginx",
+      "backing_indices" : 1,
+      "store_size_bytes" : 208,
+      "maximum_timestamp" : 0
+    }
+  ]
+}
+```
+
+### Step 3: Ingest data into the data stream
+
+To ingest data into a data stream, you can use the regular indexing APIs. Make sure every document that you index has a timestamp field. If you try to ingest a document that doesn't have a timestamp field, you get an error.
+
+```json
+POST logs-redis/_doc
+{
+  "message": "login attempt",
+  "@timestamp": "2013-03-01T00:00:00"
+}
+```
+
+### Step 4: Searching a data stream
+
+You can search a data stream just like you search a regular index or an index alias.
+The search operation applies to all of the backing indices (all data present in the stream).
+
+```json
+GET logs-redis/_search
+{
+  "query": {
+    "match": {
+      "message": "login"
+    }
+  }
+}
+```
+
+#### Sample response
+
+```json
+{
+  "took" : 514,
+  "timed_out" : false,
+  "_shards" : {
+    "total" : 5,
+    "successful" : 5,
+    "skipped" : 0,
+    "failed" : 0
+  },
+  "hits" : {
+    "total" : {
+      "value" : 1,
+      "relation" : "eq"
+    },
+    "max_score" : 0.2876821,
+    "hits" : [
+      {
+        "_index" : ".ds-logs-redis-000001",
+        "_type" : "_doc",
+        "_id" : "-rhVmXoBL6BAVWH3mMpC",
+        "_score" : 0.2876821,
+        "_source" : {
+          "message" : "login attempt",
+          "@timestamp" : "2013-03-01T00:00:00"
+        }
+      }
+    ]
+  }
+}
+```
+
+### Step 5: Rollover a data stream
+
+A rollover operation creates a new backing index that becomes the data stream’s new write index.
+
+To perform manual rollover operation on the data stream:
+
+```json
+POST logs-redis/_rollover
+```
+
+#### Sample response
+
+```json
+{
+  "acknowledged" : true,
+  "shards_acknowledged" : true,
+  "old_index" : ".ds-logs-redis-000001",
+  "new_index" : ".ds-logs-redis-000002",
+  "rolled_over" : true,
+  "dry_run" : false,
+  "conditions" : { }
+}
+```
+
+If you now perform a `GET` operation on the `logs-redis` data stream, you see that the generation ID is incremented from 1 to 2.
+
+You can also set up an [Index State Management (ISM) policy]({{site.url}}{{site.baseurl}}/im-plugin/ism/policies/) to automate the rollover process for the data stream.  
+The ISM policy is applied to the backing indices at the time of their creation. When you associate a policy to a data stream, it only affects the future backing indices of that data stream.
+
+You also don’t need to provide the `rollover_alias` setting, because the ISM policy infers this information from the backing index.
+
+### Step 6: Manage data streams in OpenSearch Dashboards
+
+To manage data streams from OpenSearch Dashboards, open **OpenSearch Dashboards**, choose **Index Management**, select **Indices** or **Policy managed indices**.
+
+You see a toggle switch for data streams that you can use to show or hide indices belonging to a data stream.
+
+When you enable this switch, you see a data stream multi-select dropdown menu that you can use for filtering data streams.
+You also see a data stream column that shows you the name of the data stream the index is contained in.
+
+![data stream toggle]({{site.url}}{{site.baseurl}}/images/data_streams_toggle.png)
+
+You can select one or more data streams and apply an ISM policy on them. You can also apply a policy on any individual backing index.
+
+You can performing visualizations on a data stream just like you would on a regular index or index alias.
+
+### Step 7: Delete a data stream
+
+The delete operation first deletes the backing indices of a data stream and then deletes the data stream itself.
+
+To delete a data stream and all of its hidden backing indices:
+
+```json
+DELETE _data_stream/<name_of_data_stream>
+```
+
+You can use wildcards to delete more than one data stream.
+
+We recommend deleting data from a data stream using an ISM policy.
+
+You can also use [asynchronous search]({{site.url}}{{site.baseurl}}/search-plugins/async/index/) and [SQL]({{site.url}}{{site.baseurl}}/search-plugins/sql/index/) and [PPL]({{site.url}}{{site.baseurl}}/search-plugins/ppl/index/) to query your data stream directly. You can also use the security plugin to define granular permissions on the data stream name.

+# Date math support for index names
+
+Date math is shorthand arithmetic for finding relative dates.
+
+If you're indexing time-series data with the dates mapped in the index names, you can use date math in your queries to filter index names and limit the number of searched indices.
+
+## Date math syntax
+
+The date math syntax for an index name is as follows:
+
+```
+<static_name{date_math_expr{date_format|time_zone}}>
+```
+
+- `static_name`: The unchanged or static portion of the index name. To use the characters `{` and `}` in the static part of an index name, escape them with a backslash `\`.
+- `date_math_expr`: The changing or dynamic portion of the index name that’s computed by the date math expression. For example, `now+1h` adds one hour, `now-1d` subtracts one hour, and `now/d` rounds down to the nearest day, where `now` represents the current timestamp.
+- `date_format`: (Optional) Specify the format for the computed date. The default value is `YYYY.MM.dd`. Make sure that you’re using the correct small or capital letters in the date format. For example, `mm` denotes minute of hour, while `MM` denotes month of year. Similarly, `hh` denotes the hour in the `1-12` range in combination with AM/PM, while `HH` denotes the hour in the `0-23` 24-hour range.
+- `time_zone`: (Optional) Specify the timezone offset. The default value is UTC. For example, the UTC time offset for PST is `-08:00`.
+
+## Date math example
+
+You must enclose date math index names within angle brackets.
+
+If today is 22nd March, 2024:
+
+- `<logstash-{now/d}>` resolves to `logstash-2024.03.22`
+- `<logstash-{now/M}>` resolves to `logstash-2024.03.01`
+- `<logstash-{now/M{YYYY.MM}}>` resolves to `logstash-2024.03`
+- `<logstash-{now/M-1M{YYYY.MM}}>` resolves to `logstash-2024.02`
+- `<logstash-{now/d{yyyy.MM.dd|+12:00}}>` resolves to `logstash-2024.03.23`
+
+You need to encode all special characters in URI format:
+
+Special characters | URI format
+:--- | :---
+`<` | %3C
+`>` | %3E
+`/` | %2F
+`{` | %7B
+`}` | %7D
+`|` | %7C
+`+` | %2B
+`:` | %3A
+`,` | %2C
+`\` | %5C
+
+If you are searching for errors in your daily logs with the default Logstash index name format `logstash-YYYY.MM.dd`, you can use date math to restrict the search to indices of the past three days:
+
+```
+# GET <logstash-{now/d-2d}>,<logstash-{now/d-1d}>,<logstash-{now/d}>/_search
+GET %3Clogstash-%7Bnow%2Fd-2d%7D%3E%2C%3Clogstash-%7Bnow%2Fd-1d%7D%3E%2C%3Clogstash-%7Bnow%2Fd%7D%3E/_search
+```
+
+This date math expression is evaluated at runtime.

+## Composable index templates
+
+Managing multiple index templates has the following challenges:
+
+- If you have duplication between index templates, storing these index templates results in a bigger cluster state.
+- If you want to make a change across all your index templates, you have to manually make the change for each template.
+- If an index matches multiple templates, OpenSearch might merge the templates in an unexpected way that you discover only after an index is created.
+
+You can use composable index templates to overcome these challenges. Composable index templates let you abstract common settings, mappings, and aliases into a reusable building block called a component template.
+
+You can combine component templates to compose an index template.
+
+Settings and mappings that you specify directly in the [create index]({{site.url}}{{site.baseurl}}/opensearch/rest-api/create-index/) request override any settings or mappings specified in an index template and its component templates.
+{: .note }
+
+### Create a component template
+
+Let's define two component templates⁠---`component_template_1` and `component_template_2`:
+
+#### Component template 1
+
+```json
+PUT _component_template/component_template_1
+{
+  "template": {
+    "mappings": {
+      "properties": {
+        "@timestamp": {
+          "type": "date"
+        }
+      }
+    }
+  }
+}
+```
+
+#### Component template 2
+
+```json
+PUT _component_template/component_template_2
+{
+  "template": {
+    "mappings": {
+      "properties": {
+        "ip_address": {
+          "type": "ip"
+        }
+      }
+    }
+  }
+}
+```
+
+### Use component templates to create an index template
+
+When creating index templates, you need to include the component templates in a `composed_of` list.
+
+OpenSearch applies the component templates in the order in which you specify them within the index template. The settings, mappings, and aliases that you specify inside the index template are applied last.
+
+```json
+PUT _index_template/daily_logs
+{
+  "index_patterns": [
+    "logs-2020-01-*"
+  ],
+  "template": {
+    "aliases": {
+      "my_logs": {}
+    },
+    "settings": {
+      "number_of_shards": 2,
+      "number_of_replicas": 1
+    },
+    "mappings": {
+      "properties": {
+        "timestamp": {
+          "type": "date",
+          "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
+        },
+        "value": {
+          "type": "double"
+        }
+      }
+    }
+  },

+    "component_template_2"
+  ],
+  "version": 3,
+  "_meta": {
+    "description": "using component templates"
+  }
+}
+```
+
+If you create an index named `logs-2020-01-01`, you can see that it derives its mappings and settings from both the component templates:
+
+```json
+PUT logs-2020-01-01
+GET logs-2020-01-01
+```
+
+#### Sample response

+          "type": "date",
+          "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
+        },
+        "value": {
+          "type": "double"
+        }
+      }
+    },
+    "settings": {
+      "index": {
+        "creation_date": "1625382479459",
+        "number_of_shards": "2",
+        "number_of_replicas": "1",

+        },
+        "provided_name": "logs-2020-01-01"
+      }
+    }
+  }
+}
+```
+
+### Simulate multi-component templates
+
+For index templates composed of multiple component templates, you can simulate applying a new template to verify whether the settings are applied as you expect.
+
+To simulate the settings that would be applied to a specific index name:
+
+```json
+POST _index_template/_simulate_index/<index_name>
+```
+
+To simulate the settings that would be applied from an existing template:
+
+```json
+POST _index_template/_simulate/<index_template>
+```
+
+You can also specify a template definition in the simulate request:
+
+```json
+POST _index_template/_simulate
+{
+  "index_patterns": [
+    "logs-2020-01-*"
+  ],
+  "template": {
+    "settings" : {
+        "index.number_of_shards" : 3
+    }
+  },
+  "composed_of": ["component_template_1", "component_template_2"]
+}
+```
+
+The `_simulate` API returns the final settings, mappings, and aliases that will be applied to indices that match the index pattern. You can also see any overlapping templates whose configuration is superseded by the simulated template body or higher priority templates:
+
+```json
+{
+  "template" : {
+    "settings" : {
+      "index" : {
+        "number_of_shards" : "3"
+      }
+    },
+    "mappings" : {
+      "properties" : {
+        "@timestamp" : {
+          "type" : "date"
+        },
+        "ip_address" : {
+          "type" : "ip"
+        }
+      }
+    },
+    "aliases" : { }
+  },
+  "overlapping" : [
+    {
+      "name" : "daily_logs",
+      "index_patterns" : [
+        "logs-2020-01-*"
+      ]
+    }
+  ]
+}
+```
+
 ## Index template options
 
 You can specify the following template options:
 
 Option | Type | Description | Required
 :--- | :--- | :--- | :---
-`priority` | `Number` | The priority of the index template.  | No
-`create` | `Boolean` | Whether this index template should replace an existing one. | No
+`template` | `Object` |  Specify index settings, mappings, and aliases. | No
+`priority` | `Integer` | The priority of the index template.  | No
+`composed_of` | `String array` |  The names of component templates applied on a new index together with the current template.  | No
+`version` | `Integer` | Specify a version number to simplify template management. Default is `null`. | No
+`_meta ` | `Object` | Specify meta information about the template. | No

+# Run OpenSearch using Helm
+
+Helm is a package manager that allows you to easily install and manage OpenSearch in a Kubernetes cluster. You can define your OpenSearch configurations in a YAML file and use Helm to deploy your applications in a version-controlled and reproducible way.
+
+The Helm chart contains the resources described in the following table.
+
+Resource | Description
+:--- | :---
+`Chart.yaml` |  Information about the chart.
+`values.yaml` |  Default configuration values for the chart.
+`templates` |  Templates that combine with values to generate the Kubernetes manifest files.
+
+The specification in the default Helm chart supports many standard use cases and setups. You can modify the default chart to configure your desired specifications and set Transport Layer Security (TLS) and role-based access control (RBAC).
+
+For information about the default configuration, steps to configure security, and configurable parameters, see the
+[README](https://github.com/opensearch-project/opensearch-devops/blob/main/Helm/README.md).
+
+The instructions here assume you have a Kubernetes cluster with Helm preinstalled. See the [Kubernetes documentation](https://kubernetes.io/docs/setup/) for steps to configure a Kubernetes cluster and the [Helm documentation](https://helm.sh/docs/intro/install/) to install Helm.
+{: .note }
+
+## Prerequisites
+
+The default Helm chart deploys a three-node cluster. We recommend that you have at least 8 GiB of memory available for this deployment. You can expect the deployment to fail if, say, you have less than 4 GiB of memory available.
+
+## Install OpenSearch using Helm
+
+1. Clone the [opensearch-devops](https://github.com/opensearch-project/opensearch-devops/) repository:
+
+   ```bash
+   git clone https://github.com/opensearch-project/opensearch-devops.git
+   ```
+
+1. Change to the `opensearch` directory:
+
+   ```bash
+   cd Helm/opensearch
+   ```
+
+1. Package the Helm chart:
+
+   ```bash
+   helm package .
+   ```
+
+1. Deploy OpenSearch:
+
+   ```bash
+   helm install --generate-name opensearch-1.0.0.tgz
+   ```
+   The output shows you the specifications instantiated from the install.
+   To customize the deployment, pass in the values that you want to override with a custom YAML file:
+
+   ```bash
+   helm install --values=customvalues.yaml opensearch-1.0.0.tgz
+   ```
+
+#### Sample output

+
+To access the OpenSearch shell:
+
+```bash
+$ kubectl exec -it opensearch-cluster-master-0 -- /bin/bash

 The OpenSearch logs include valuable information for monitoring cluster operations and troubleshooting issues. The location of the logs differs based on the installation type:
 
 - On Docker, OpenSearch writes most logs to the console and stores the remainder in `opensearch/logs/`. The tarball installation also uses `opensearch/logs/`.
-- On the RPM and Debian installations, OpenSearch writes logs to `/var/log/opensearch/`.

+Logs are available as `.log` (plain text) and `.json` files. Permissions for the OpenSearch logs are `-rw-r--r--` by default, meaning that any user account on the node can read them. You can change this behavior _for each log type_ in `log4j2.properties` using the `filePermissions` option. For example, you might add `appender.rolling.filePermissions = rw-r-----` to change permissions for the JSON server log.

+# cat API
+
+You can get essential statistics about your cluster in an easy-to-understand, tabular format using the compact and aligned text (CAT) API. The cat API is a human-readable interface that returns plain text instead of traditional JSON.
+
+Using the cat API, you can answer questions like which node is the elected master, what state is the cluster in, how many documents are in each index, and so on.
+
+## Example
+
+To see the available operations in the cat API, use the following command:
+
+```
+GET _cat
+```
+
+## Common URL parameters
+
+You can use the following string parameters with your query.
+
+Parameter | Description
+:--- | :--- |
+`?v` |  Makes the output more verbose by adding headers to the columns. It also adds some formatting to help align each of the columns together. All examples in this section include the `v` parameter.
+`?help` | Lists the default and other available headers for a given operation.
+`?h`  |  Limits the output to specific headers.
+`?format` |  Outputs the result in JSON, YAML, or CBOR formats.
+`?sort` | Sorts the output by the specified columns.
+
+To see what each column represents, use the `?v` parameter:
+
+```
+GET _cat/<operation_name>?v
+```
+
+To see all the available headers, use the `?help` parameter:
+
+```
+GET _cat/<operation_name>?help
+```
+
+To limit the output to a subset of headers, use the `?h` parameter:
+
+```
+GET _cat/<operation_name>?h=<header_name_1>,<header_name_2>&v
+```
+
+Typically, for any operation you can find out what headers are available using the `?help` parameter, and then use the `?h` parameter to limit the output to only the headers that you care about.
+
+If you use the security plugin, make sure you have the appropriate permissions.

+
+Parameter | Type | Description
+:--- | :--- | :---
+include_type_name | Boolean | If `true`, the request expects a type in the body of mappings. Because OpenSearch indices all have a type of `_doc`, we recommend that this parameter is left as the default of `false.`
+wait_for_active_shards | String | Specifies the number of active shards that must be available before OpenSearch processes the request. Default is 1 (only the primary shard). Set to `all` or a positive integer. Values greater than 1 require replicas. For example, if you specify a value of 3, the index must have two replicas distributed across two additional nodes for the request to succeed.
+master_timeout | Time | How long to wait for a connection to the master node. Default is `30s`.
+timeout | Time | How long to wait for the request to return. Default is `30s`.
+
+## Request body
+
+As part of your request, you can supply parameters in your request's body that specify index settings, mappings, and [aliases]({{site.url}}{{site.baseurl}}/opensearch/index-alias/) for your newly created index. The following sections provide more information about index settings and mappings.
+
+
+### Index settings
+
+Index settings are separated into two varieties: static index settings and dynamic index settings. Static index settings are settings that you specify at index creation and can't change later. You can change dynamic settings at any time, including at index creation.
+
+#### Static index settings
+
+Setting | Description
+:--- | :---
+index.number_of_shards | The number of primary shards in the index. Default is 1.
+index.number_of_routing_shards | The number of routing shards used to split an index.
+index.shard.check_on_startup | Whether the index's shards should be checked for corruption. Available options are `false` (do not check for corruption), `checksum` (check for physical corruption), and `true` (check for both physical and logical corruption). Default is `false`.
+index.codec | The compression type to use to compress stored data. Available values are `best_compression` and `default`.
+index.routing_partition_size | The number of shards a custom routing value can go to. Routing helps an imbalanced cluster by relocating values to a subset of shards rather than just a single shard. To enable, set this value to greater than 1 but less than `index.number_of_shards`. Default is 1.
+index.soft_deletes_enabled | Whether to retain a history of operations performed on the index.
+index.soft_deletes.retention_lease.period | The maximum amount of time to retain a shard's history of operations. Default is `12h`.
+index.load_fixed_bitset_filters_eagerly | Indicates whether cached filters should be pre-loaded for nested queries. Available options are `true` and `false`. Default is `true`.
+index.hidden | Whether the index should be hidden. Hidden indices are not returned as part of queries that have wildcards. Available options are `true` and `false`. Default is `false`.
+
+#### Dynamic index Settings
+
+Setting | Description
+:--- | :---
+index.number_of_replicas | The number of replica shards each primary shard should have. For example, if you have 4 primary shards and set `index.number_of_replicas` to 3, the index has 12 replica shards. Default is 1.
+index.auto_expand_replicas | Automatically expands the number of replicas based on the amount of data nodes in the cluster. Specify a lower bound and upper limit (for example, 0-9), or `all` for the upper limit. For example, if you have 5 data nodes and set `index.auto_expand_replicas` to 0-3, then the cluster does not autoamtically add another replica shard. However, if you set this value to `0-all` and add 2 more nodes for a total of 7, the cluster will expand to now have 6 replica shards. Default is disabled.
+index.search.idle.after | Amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
+index.refresh_interval | How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
+index.max_result_window | The maximum value of `from` + `size` for searches to the index. `from` is the starting index to search from, and `size` is the amount of results to return. Default: 10000.
+index.max_inner_result_window | The maximum value of `from` + `size` for inner hits definitions and top hits aggregations to the index. `from` is the starting index to search from, and `size` is the amount of top hits to return. Default is 100.
+index.max_rescore_window | The maximum value of `window_size` for rescore requests to the index. Rescore requests reorder the index's documents and return a new score, which can be more precise. Default is the same as index.max_inner_result_window or 10000 by default.
+index.max_docvalue_fields_search | Maximum amount of `docvalue_fields` allowed in a query. Default is 100.
+index.max_script_fields | Maximum amount of `script_fields` allowed in a query. Default is 32.
+index.max_ngram_diff | Maximum allowed difference between `min_gram` and `max_gram` values for `NGramTokenizer` and `NGramTokenFilter`. Default is 1.
+index.max_shingle_diff | Maximum allowed difference between `max_shingle_size` and `min_shingle_size` for the `shingle` token filter. Default is 3.
+index.max_refresh_listeners | Maximum amount of refresh listeners available on the index's shards.
+index.analyze.max_token_count | Maximum amount of tokens that can return from the `_analyze` API operation. Default is 10000.
+index.highlight.max_analyzed_offset | The maximum amount of characters that will be analyzed in a highlight request. Default is 1000000.
+index.max_terms_count | The maximum amount of terms that can be used in a terms query. Default is 65536.
+index.max_regex_length | The maximum character length of regex that can be in a regexp query. Default is 1000.
+index.query.default_field | A field or list of fields that OpenSearch uses in queries in case a field isn't specified in the parameters.
+index.routing.allocation.enable | Specifies options for the index's shard allocation. Available options are `all` (allow shard allocation for all shards), `primaries` (allow shard allocation only for primary shards), `new_primaries` (allow shard allocaiton only for new primary shards), and `none` (do not allow shard allocation). Default is `all`.
+index.routing.rebalance.enable | Enables shard rebalancing for the index. Available options are `all` (allow shard rebalancing for all shards), `primaries`, (allow shard rebalancing only for primary shards), `replicas` (allow shard rebalancing only for replicas), and `none` (do not allow shard rebalancing). Default is `all`.
+index.gc_deletes | Amount of time to retain a deleted document's version number. Default is `60s`.
+index.default_pipeline | The default ingest node pipeline for the index. If the default pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
+index.final_pipeline | The final ingest node pipeline for the index. If the final pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
+
+### Mappings
+
+Mappings define how a documents and its fields are stored and indexed. If you're just starting to build out your cluster and data, you may not know exactly how your data should be stored. In those cases, you can use dynamic mappings, which tell OpenSearch to dynamically add data and their fields. However, if you know exactly what types your data fall under and want to enforce that standard, then you can use explicit mappings.
+
+For example, if you want to indicate that `year` should be of type `text` instead of an `integer`, and `age` should be an `integer`, you can do so with explicit mappings. Using dynamic mapping, OpenSearch might interpret both `year` and `age` as integers.
+
+#### Dynamic mapping types
+
+Type | Description
+:--- | :---
+null | A `null` field can't be indexed or searched. When a field is set to null, OpenSearch behaves as if that field has no values.
+boolean | OpenSearch accepts `true` and `false` as boolean values. An empty string is equal to `false.`
+float | A single-precision 32-bit floating point number.
+double | A double-precision 64-bit floating point number.
+integer | A signed 32-bit number.
+object | Objects are standard JSON objects, which can have fields and mappings of their own. For example, a `movies` object can have additional properties such as `title`, `year`, and `director`.
+array | Arrays in OpenSearch can only store values of one type, such as an array of just integers or strings. Empty arrays are treated as though they are fields with no values.
+text | A string sequence of characters that represent full-text values.
+keyword | A string sequence of structured characters, such as an email or ZIP code.
+date detection string | Enabled by default, if new string fields match a date's format, then the string is processed as a `date` field. For example, `date: "2012/03/11"` is processed as a date.
+numeric detection string | If disabled, OpenSearch may automatically process numeric values as strings when they should be processed as numbers. When enabled, OpenSearch can process strings into `long`, `integer`, `short`, `byte`, `double`, `float`, `half_float`, `scaled_float`, `unsigned_long`. Default is disabled.
+
+#### Explicit mapping
+
+If you know exactly what your data's typings need to be, you can specify them in your request body when creating your index.
+
+```json
+{
+  "mappings": {
+    "properties": {
+      "year":    { "type" : "text" },
+      "age":     { "type" : "integer" },

+
+You can include a query as part of your delete request so OpenSearch deletes all documents that match that query.
+
+## Example
+
+```json
+POST sample-index1/_delete_by_query
+{
+  "query": {
+    "match": {
+      "movie-length": "124"

+```
+
+## URL parameters
+
+All URL parameters are optional.
+
+Parameter | Type | Description
+:--- | :--- | :--- | :---
+&lt;index&gt; | String | Name of the data streams, indices, or aliases to delete from. Supports wildcards. If left blank, OpenSearch searches all indices.
+allow_no_indices | Boolean | False indicates to OpenSearch the request should return an error if any wildcard expression or index alias targets only missing or closed indices. Default is true.
+analyzer | String | The analyzer to use in the query string.
+analyze_wildcard | Boolean | Specifies whether to analyze wildcard and prefix queries. Default is false.
+conflicts | String | Indicates to OpenSearch what should happen if the delete by query operation runs into a version conflict. Valid options are `abort` and `proceed`. Default is `abort`.
+default_operator | String | Indicates whether the default operator for a string query should be AND or OR. Default is OR.
+df | String | The default field in case a field prefix is not provided in the query string.
+expand_wildcards | String | Specifies the type of index that wildcard expressions can match. Supports comma-separated values. Valid values are `all` (match any index), `open` (match open, non-hidden indices), `closed` (match closed, non-hidden indices), `hidden` (match hidden indices), and `none` (deny wildcard expressions). Default is `open`.
+from | Integer | The starting index to search from. Default is 0.
+ignore_unavailable | Boolean | Specifies whether to include missing or closed indices in the response. Default is false.
+lenient | Boolean | Specifies whether OpenSearch should ignore format-based query failures (for example, querying a text field for an integer). Default is false.
+max_docs | Integer | Maximum amount of documents the operation should process. Default is all documents.
+preference | String | Specifies the shard or node OpenSearch should perform the operation on.
+q | String | Query in the Lucene query string syntax.
+request_cache | Boolean | Specifies whether OpenSearch should use the request cache for the request. Default is whether it's enabled in the index's settings.
+refresh | Boolean | Specifies whether OpenSearch should refresh all of the shards involved in the delete request once the operation finishes. Default is false.
+requests_per_second | Integer | Specifies the request's throttling in sub-requests per second. Default is -1, which means no throttling.
+routing | String | Value used to route the operation to a specific shard.
+scroll | Time | Amount of time the search context should be open.
+scroll_size | Integer | Size of the scroll request of the operation. Default is 1000.
+search_type | String | Whether OpenSearch should use global term and document frequencies calculating revelance scores. Valid choices are `query_then_fetch` and `dfs_query_then_fetch`. `query_then_fetch` scores documents using local term and document frequencies for the shard. It’s usually faster but less accurate. `dfs_query_then_fetch` scores documents using global term and document frequencies across all shards. It’s usually slower but more accurate. Default is `query_then_fetch`.
+search_timeout | Time | Amount of time until timeout for the search request. Default is no timeout.
+slices | Integer | Number of sub-tasks OpenSearch should divide this task into. Default is 1, which means OpenSearch should not divide this task.
+sort | String | A comma-separated list of &lt;field&gt; : &lt;direction&gt; pairs to sort by.
+_source | String | Specifies whether to include the `_source` field in the response.
+_source_excludes | String | A comma-separated list of source fields to exclude from the response.
+_source_includes | String | A comma-separated list of source fields to include in the response.
+stats | String | Value to associate with the request for additional logging.
+terminate_after | Integer | The maximum number of documents OpenSearch should process before terminating the request.
+timeout | Time | How long the operation should wait from a response from active shards. Default is `1m`.
+version | Boolean | Whether to include the document version as a match.
+wait_for_active_shards | String | The number of shards that must be active before OpenSearch executes the operation. Valid values are `all` or any integer up to the total number of shards in the index. Default is 1, which is the primary shard.
+
+## Request body
+
+To search your index for specific documents, you must include a [query]({{site.url}}{{site.baseurl}}/opensearch/query-dsl/index) in the request body that OpenSearch uses to match documents. If you don't use a query, OpenSearch treats your delete request as a simple [delete document operation]({{site.url}}{{site.baseurl}}/opensearch/rest-api/document-apis/delete-document).
+
+```json
+{
+  "query": {
+    "match": {
+      "movie-length": "124"
+    }
+  }
+}
+```

+# Document APIs
+
+The document APIs allow you to handle documents relative to your index, such as adding, updating, and deleting documents.
+
+Document APIs are separated into two categories: single document operations and multi-document operations. Multi-document operations offer performance advantages over submitting many individual requests, so whenever practical, we recommend that you use multi-document operations.
+
+## Single document operations
+
+- Index
+- Get
+- Delete
+- Update
+
+## Multi-document operations

+- Bulk
+- Multi get
+- Delete by query

+# Update document
+Introduced 1.0
+{: .label .label-purple }
+
+If you need to update a document's fields in your index, you can use the update document API operation. You can do so by specifying the new data you want in your index or by including a script in your request body, which OpenSearch runs to update the document.
+
+## Example
+
+```json
+POST /sample-index1/_update/1
+{
+  "doc": {
+    "first_name" : "Bruce",
+    "last_name" : "Wayne"
+  }
+}
+```
+
+## Script example
+
+```json
+POST /test-index1/_update/1
+{
+  "script" : {
+    "source": "ctx._source.oldValue += params.newValue",
+    "lang": "painless",
+    "params" : {
+      "newValue" : 10
+    }
+  }
+}
+```
+
+## Path and HTTP methods
+
+```
+POST /<index-name>/_update/<_id>
+```
+
+## URL parameters
+
+Parameter | Type | Description | Required
+:--- | :--- | :--- | :---
+&lt;index-name&gt; | String | Name of the index. | Yes
+&lt;_id&gt; | String | The ID of the document to update. | Yes
+if_seq_no | Integer | Only perform the delete operation if the document's version number matches the specified number. | No
+if_primary_term | Integer | Only perform the delete operation if the document has the specified primary term. | No
+lang | String | Language of the script. Default is `painless`. | No
+require_alias | Boolean | Specifies whether the destination must be an index alias. Default is false. | No
+refresh | Enum | If true, OpenSearch refreshes shards to make the operation visible to searching. Valid options are `true`, `false`, and `wait_for`, which tells OpenSearch to wait for a refresh before executing the operation. Default is false. | No
+retry_on_conflict | Integer | The amount of times OpenSearch should retry the operation if there's a document conflict. Default is 0. | No
+routing | String | Value used to route the operation to a specific shard. | No
+_source | List | Whether to include the `_source` field in the response body. Default is true. | No
+_source_excludes | List | A comma-separated list of source fields to exclude in the query response. | No
+_source_includes | List | A comma-separated list of source fields to include in the query response. | No
+timeout | Time | How long to wait for a response from the cluster. | No
+wait_for_active_shards | String | The number of active shards that must be available before OpenSearch processes the update request. Default is 1 (only the primary shard). Set to `all` or a positive integer. Values greater than 1 require replicas. For example, if you specify a value of 3, the index must have two replicas distributed across two additional nodes for the operation to succeed. | No
+
+## Request body
+
+Your request body must contain the information you want to update your document with. If you just want to replace certain fields in your document, your request body must include a `doc` object, which has the fields you want to update.
+
+```json
+{
+  "doc": {
+    "first_name": "Thomas",
+    "last_name": "Wayne"
+    }
+}
+```
+
+You can also use a script to tell OpenSearch how to update your document.
+
+```json
+{
+  "script" : {
+    "source": "ctx._source.oldValue += params.newValue",
+    "lang": "painless",
+    "params" : {
+      "newValue" : 10
+    }
+  }
+}
+```
+
+## Response
