-= Spring Data for Elasticsearch image:https://img.shields.io/badge/Revved%20up%20by-Develocity-06A0CE?logo=Gradle&labelColor=02303A["Revved up by Develocity", link="https://ge.spring.io/scans?search.rootProjectNames=Spring Data Elasticsearch"]
-
-The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
-
-The Spring Data Elasticsearch project provides integration with the https://www.elastic.co/[Elasticsearch] search engine.
-Key functional areas of Spring Data Elasticsearch are a POJO centric model for interacting with Elasticsearch Documents and easily writing a Repository style data access layer.
-
-This project is lead and maintained by the community.
-
-== Features
-
-* Spring configuration support using Java based `@Configuration` classes or an XML namespace for an ES client instances.
-* `ElasticsearchOperations` class and implementations that increases productivity performing common ES operations.
-Includes integrated object mapping between documents and POJOs.
-* Feature Rich Object Mapping integrated with Spring’s Conversion Service
-* Annotation based mapping metadata
-* Automatic implementation of `Repository` interfaces including support for custom search methods.
-* CDI support for repositories
-
-include::https://raw.githubusercontent.com/spring-projects/spring-data-build/refs/heads/main/etc/readme/code-of-conduct.adoc[]
-
-== Getting Started
-
-Here is a quick teaser of an application using Spring Data Repositories in Java:
-
-[source,java]
-----
-public interface PersonRepository extends CrudRepository<Person, Long> {
-
-  List<Person> findByLastname(String lastname);
-
-  List<Person> findByFirstnameLike(String firstname);
-}
-
-@Service
-public class MyService {
-
-  private final PersonRepository repository;
-
-  public MyService(PersonRepository repository) {
-    this.repository = repository;
-  }
-
-  public void doWork() {
-
-    repository.deleteAll();
-
-    Person person = new Person();
-    person.setFirstname("Oliver");
-    person.setLastname("Gierke");
-    repository.save(person);
-
-    List<Person> lastNameResults = repository.findByLastname("Gierke");
-    List<Person> firstNameResults = repository.findByFirstnameLike("Oli");
- }
-}
-----
-
-=== Using the RestClient
-
-Please check the https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.clients.configuration[official documentation].
-
-include::https://raw.githubusercontent.com/spring-projects/spring-data-build/refs/heads/main/etc/readme/dependencies.adoc[]
-
-**Compatibility Matrix**
-
-The compatibility between Spring Data Elasticsearch, Elasticsearch client drivers and Spring Boot versions can be found in the https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.versions[reference documentation].
-
-To use the Release candidate versions of the upcoming major version, use our Maven milestone repository and declare the appropriate dependency version:
-
-[source,xml]
-----
-<dependency>
-  <groupId>org.springframework.data</groupId>
-  <artifactId>spring-data-elasticsearch</artifactId>
-  <version>${version}.RCx</version> <!-- x being 1, 2, ... -->

 == Running CI tasks locally
 
-You can run CI jobs locally using Docker and act[https://nektosact.com/].
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your `verify.sh` script before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-elasticsearch-github adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-elasticsearch-github`.
++
+2. `cd spring-data-elasticsearch-github`
++
+Next, run your tests from inside the container:
++
+3. `./mvnw clean dependency:list test -Dsort` (or whatever profile you need to test out)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+If you need to package things up, do this:
+
+1. `docker run -it -v /var/run/docker.sock:/var/run/docker.sock --mount type=bind,source="$(pwd)",target=/spring-data-elasticsearch-github adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-elasticsearch-github`.
++
+2. `cd spring-data-elasticsearch-github`
++
+Next, try to package everything up from inside the container:
++
+3. `./mvnw -Pci,snapshot -Dmaven.test.skip=true clean package`
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

 Although the Elasticsearch Client can be used directly to work with the cluster, applications using Spring Data Elasticsearch normally use the higher level abstractions of xref:elasticsearch/template.adoc[Elasticsearch Operations] and xref:elasticsearch/repositories/elasticsearch-repositories.adoc[Elasticsearch Repositories].

-NOTE: Although `SearchTemplateQuery` is an implementation of the `Query` interface, not all of the functionality provided by the base class is available for a `SearchTemplateQuery` like setting a `Pageable` or a `Sort`. Values for this functionality must be added to the stored script like shown in the following example for paging parameters. If these values are set on the `Query` object, they will be ignored.

 About the filter query: It is not possible to use a `CriteriaQuery` here, as this query would be converted into a Elasticsearch nested query which does not work in the filter context. So only `StringQuery` or `NativeQuery` can be used here. When using one of these, like the term query above, the Elasticsearch field names must be used, so take care, when these are redefined with the `@Field(name="...")` definition.
