-
-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:

 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].

-[[elasticsearch-migration-guide-5.5-6.0.breaking-changes]]
-== Breaking Changes
-
-From version 6.0 on, Spring Data Elasticsearch uses the Elasticsearch 9 libraries and as default the new `Rest5Client` provided by these libraries. It is still possible to use the old `RestClient`, check xref:elasticsearch/clients.adoc[Elasticsearch clients] for information. The configuration callbacks for this `RestClient` have been moved from `org.springframework.data.elasticsearch.client.elc.ElasticsearchClients` to the `org.springframework.data.elasticsearch.client.elc.rest_client.RestClients` class.
-
-In the `org.springframework.data.elasticsearch.core.query.UpdateQuery` class the type of the two fields `ifSeqNo` and `ifPrimaryTerm` has changed from `Integer` to `Long` to align with the normal query and the underlying Elasticsearch client.
-
-[[elasticsearch-migration-guide-5.5-6.0.deprecations]]

-
-All the code using the old `RestClient` has been moved to the `org.springframework.data.elasticsearch.client.elc.rest_client` package and has been deprecated. Users should switch to the classes from the `org.springframework.data.elasticsearch.client.elc.rest5_client` package.
-
-
-=== Removals
-
-The `org.springframework.data.elasticsearch.core.query.ScriptType` enum has been removed. To distinguish between an inline and a stored script set the appropriate values in the `org.springframework.data.elasticsearch.core.query.ScriptData` record.
-
