 == Running CI tasks locally
 
 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.
+* Test out a a tweak to your `test.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.

-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.

-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-= Testing
-
-== Unit tests
-
-Unit tests in the project are run with
-
-----
-./mvnw test
-----
-
-== Integration tests
-
-Integration tests are executed when
-----
-./mvnw verify
-----
-is run. There must be _docker_ running, as the integration tests use docker to start an Elasticsearch server.
-
-Integration tests are tests that have the Junit5 Tag `@Tag("integration-test")` on the test class. Normally this should not be set explicitly, but the annotation `@SpringIntegrationTest` should be used. This not only marks the test as integration test, but integrates an automatic setup of an Elasticsearch Testcontainer and integrate this with Spring, so
-that the required Beans can be automatically injected. Check _src/test/java/org/springframework/data/elasticsearch/JUnit5SampleRestClientBasedTests.java_ as a reference setup
-
-== Mutation testing
-
-The pom includes a plugin dependency to run mutation tests using [pitest](https://pitest.org/). These tests must be explicitly configured and run, they are not included in the normal build steps. Before pitest can run, a normal `./mvnw test` must be executed. The configuration excludes integration tests, only unit tests are considered.
-
-
-pitest can be run directly from the commandline
-----
-./mvnw org.pitest:pitest-maven:mutationCoverage
-----
-This will output an html report to _target/pit-reports/YYYYMMDDHHMI_.
-
-To speed-up repeated analysis of the same codebase set the withHistory parameter to true.
-----
-./mvnw -DwithHistory org.pitest:pitest-maven:mutationCoverage

-
-The classes to test are defined either in the pom.xml or can be set on the commandline:

+
+This chapter includes details of the Elasticsearch repository implementation.
+
+[[elasticsearch.introduction]]
+== Introduction
+
+[[elasticsearch.namespace]]
+=== Spring Namespace
+
+The Spring Data Elasticsearch module contains a custom namespace allowing definition of repository beans as well as elements for instantiating a `ElasticsearchServer` .
+
+Using the `repositories` element looks up Spring Data repositories as described in <<repositories.create-instances>> .
+
+.Setting up Elasticsearch repositories using Namespace

+
+[[elasticsearch.annotation]]
+=== Annotation based configuration
+
+The Spring Data Elasticsearch repositories support cannot only be activated through an XML namespace but also using an annotation through JavaConfig.
+
+.Spring Data Elasticsearch repositories using JavaConfig
+====
+[source,java]
+----
+@Configuration
+@EnableElasticsearchRepositories(basePackages = "org/springframework/data/elasticsearch/repositories")
+static class Config {
+
+    @Bean
+    public ElasticsearchOperations elasticsearchTemplate() {
+        return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
+    }
+}                
+----
+====
+
+The configuration above sets up an `Embedded Elasticsearch Server` which is used by the `ElasticsearchTemplate` . Spring Data Elasticsearch Repositories are activated using the `@EnableElasticsearchRepositories` annotation, which essentially carries the same attributes as the XML namespace does. If no base package is configured, it will use the one the configuration class resides in.
+
+[[elasticsearch.cdi]]
+=== Elasticsearch Repositores using CDI
+
+The Spring Data Elasticsearch repositories can also be set up using CDI functionality.
+
+.Spring Data Elasticsearch repositories using JavaConfig
+====
+[source,java]
+----
+class ElasticsearchTemplateProducer {
+
+    @Produces
+    @ApplicationScoped
+    public ElasticsearchOperations createElasticsearchTemplate() {
+        return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
+    }
+}
+
+class ProductService {
+
+    private ProductRepository repository;
+
+    public Page<Product> findAvailableBookByName(String name, Pageable pageable) {
+        return repository.findByAvailableTrueAndNameStartingWith(name, pageable);
+    }
+
+    @Inject
+    public void setRepository(ProductRepository repository) {
+        this.repository = repository;
+    }
+}                
+----
+====
+
+[[elasticsearch.query-methods]]
+== Query methods
+
+[[elasticsearch.query-methods.finders]]
+=== Query lookup strategies
+
+The Elasticsearch module supports all basic query building  feature as String,Abstract,Criteria or have it being derived from the method name.
+
+==== Declared queries
+
+Deriving the query from the method name is not always sufficient and/or may result in unreadable method names. In this case one might make either use of `@Query` annotation (see <<elasticsearch.query-methods.at-query>> ).
+
+[[elasticsearch.query-methods.criterions]]
+=== Query creation
+
+Generally the query creation mechanism for Elasticsearch works as described in <<repositories.query-methods>> . Here's a short example of what a Elasticsearch query method translates into: 
+
+.Query creation from method names
+====
+[source,java]
+----
+public interface BookRepository extends Repository<Book, String>
+{
+    List<Book> findByNameAndPrice(String name, Integer price);
+}                
+----
+====
+
+The method name above will be translated into the following Elasticsearch json query
+
+[source]
+----
+{ "bool" :
+    { "must" :
+        [
+            { "field" : {"name" : "?"} },
+            { "field" : {"price" : "?"} }
+        ] 
+    }
+}                    
+----
+
+A list of supported keywords for Elasticsearch is shown below. 
+
+[cols="1,2,3", options="header"]

-== Elasticsearch Auditing
-
-=== Preparing entities
-
-In order for the auditing code to be able to decide whether an entity instance is new, the entity must implement the `Persistable<ID>` interface which is defined as follows:
-
-[source,java]
-----
-package org.springframework.data.domain;
-
-import org.springframework.lang.Nullable;
-
-public interface Persistable<ID> {
-    @Nullable
-    ID getId();
-
-    boolean isNew();
-}
-----
-
-As the existence of an Id is not a sufficient criterion to determine if an enitity is new in Elasticsearch, additional information is necessary. One way is to use the creation-relevant auditing fields for this decision:
-
-A `Person` entity might look as follows - omitting getter and setter methods for brevity:
-
-[source,java]
-----
-@Document(indexName = "person")
-public class Person implements Persistable<Long> {
-    @Id private Long id;
-    private String lastName;
-    private String firstName;
-    @CreatedDate
-    @Field(type = FieldType.Date, format = DateFormat.basic_date_time)
-    private Instant createdDate;
-    @CreatedBy
-    private String createdBy
-    @Field(type = FieldType.Date, format = DateFormat.basic_date_time)
-    @LastModifiedDate
-    private Instant lastModifiedDate;
-    @LastModifiedBy
-    private String lastModifiedBy;
-
-    public Long getId() {                                                 // <.>
-        return id;
-    }
-
-    @Override
-    public boolean isNew() {
-        return id == null || (createdDate == null && createdBy == null);  // <.>
-    }
-}
-----
-<.> the getter is the required implementation from the interface
-<.> an object is new if it either has no `id` or none of fields containing creation attributes are set.
-
-=== Activating auditing
-
-After the entities have been set up and providing the `AuditorAware` - or `ReactiveAuditorAware` - the Auditing must be activated by setting the `@EnableElasticsearchAuditing` on a configuration class:
-
-[source,java]
-----
-@Configuration
-@EnableElasticsearchRepositories
-@EnableElasticsearchAuditing
-class MyConfiguration {
-   // configuration code
-}
-----
-
-When using the reactive stack this must be:
-[source,java]
-----
-@Configuration
-@EnableReactiveElasticsearchRepositories
-@EnableReactiveElasticsearchAuditing
-class MyConfiguration {
-   // configuration code
-}
-----
-
-If your code contains more than one `AuditorAware` bean for different types, you must provide the name of the bean to use as an argument to the `auditorAwareRef` parameter of the 
- `@EnableElasticsearchAuditing` annotation.

-= Elasticsearch Clients
-
-This chapter illustrates configuration and usage of supported Elasticsearch client implementations.
-
-Spring Data Elasticsearch operates upon an Elasticsearch client that is connected to a single Elasticsearch node or a cluster. Although the Elasticsearch Client can be used to work with the cluster, applications using Spring Data Elasticsearch normally use the higher level abstractions of <<elasticsearch.operations>> and <<elasticsearch.repositories>>.
-
-[[elasticsearch.clients.transport]]
-== Transport Client
-
-WARNING: The `TransportClient` is deprecated as of Elasticsearch 7 and will be removed in Elasticsearch 8. (https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html[see the Elasticsearch documentation]). Spring Data Elasticsearch will support the `TransportClient` as long as it is available in the used
-Elasticsearch <<elasticsearch.versions,version>> but has deprecated the classes using it since version 4.0.
-
-We strongly recommend to use the <<elasticsearch.clients.rest>> instead of the `TransportClient`.

-
-The Java High Level REST Client is the default client of Elasticsearch, it provides a straight forward replacement for the `TransportClient` as it accepts and returns

-<.> Optionally set a path prefix, mostly used when different clusters a behind some reverse proxy.
-<.> Set the connection timeout. Default is 10 sec.
-<.> Set the socket timeout. Default is 5 sec.
-<.> Optionally set headers.
-<.> Add basic authentication.
-<.> A `Supplier<Header>` function can be specified which is called every time before a request is sent to Elasticsearch - here, as an example, the current time is written in a header.
-<.> for reactive setup a function configuring the `WebClient`
-<.> for non-reactive setup a function configuring the REST client
-====
-
-IMPORTANT: Adding a Header supplier as shown in above example allows to inject headers that may change over the time, like authentication JWT tokens. If this is used in the reactive setup, the supplier function *must not* block!

-= Upgrading from 3.2.x to 4.0.x
-
-This section describes breaking changes from version 3.2.x to 4.0.x and how removed features can be replaced by new introduced features.
-
-[[elasticsearch-migration-guide-3.2-4.0.jackson-removal]]
-== Removal of the used Jackson Mapper
-
-One of the changes in version 4.0.x is that Spring Data Elasticsearch does not use the Jackson Mapper anymore to map an entity to the JSON representation needed for Elasticsearch (see <<elasticsearch.mapping>>). In version 3.2.x the Jackson Mapper was the default that was used. It was possible to switch to the meta-model based converter (named `ElasticsearchEntityMapper`) by explicitly configuring it (<<elasticsearch.mapping.meta-model>>).
-
-In version 4.0.x the meta-model based converter is the only one that is available and does not need to be configured explicitly. If you had a custom configuration to enable the meta-model converter by providing a bean like this:
-
-[source,java]
-----
-@Bean
-@Override
-public EntityMapper entityMapper() {
-
-  ElasticsearchEntityMapper entityMapper = new ElasticsearchEntityMapper(
-    elasticsearchMappingContext(), new DefaultConversionService()
-  );
-  entityMapper.setConversions(elasticsearchCustomConversions());
-
-  return entityMapper;
-}
-----
-
-You now have to remove this bean, the `ElasticsearchEntityMapper` interface has been removed.
-
-.Entity configuration
-Some users had custom Jackson annotations on the entity class, for example in order to define a custom name for the mapped document in Elasticsearch or to configure date conversions. These are not taken into account anymore. The needed functionality is now provided with Spring Data Elasticsearch's `@Field` annotation. Please see <<elasticsearch.mapping.meta-model.annotations>> for detailed information.
-
-[[elasticsearch-migration-guide-3.2-4.0.implicit-index-name]]
-== Removal of implicit index name from query objects
-
-In 3.2.x the different query classes like `IndexQuery` or `SearchQuery` had properties that were taking the index name or index names that they were operating upon. If these were not set, the passed in entity was inspected to retrieve the index name that was set in the `@Document` annotation. +
-In 4.0.x the index name(s) must now be provided in an additional parameter of type `IndexCoordinates`. By separating this, it now is possible to use one query object against different indices.
-
-So for example the following code:
-
-[source,java]
-----
-IndexQuery indexQuery = new IndexQueryBuilder()
-  .withId(person.getId().toString())
-  .withObject(person)
-  .build();
-
-String documentId = elasticsearchOperations.index(indexQuery);
-----
-
-must be changed to:
-
-[source,java]
-----
-IndexCoordinates indexCoordinates = elasticsearchOperations.getIndexCoordinatesFor(person.getClass());
-
-IndexQuery indexQuery = new IndexQueryBuilder()
-  .withId(person.getId().toString())
-  .withObject(person)
-  .build();
-
-String documentId = elasticsearchOperations.index(indexQuery, indexCoordinates);
-----
-
-To make it easier to work with entities and use the index name that is contained in the entitie's `@Document` annotation, new methods have been added like `DocumentOperations.save(T entity)`;
-
-[[elasticsearch-migration-guide-3.2-4.0.new-operations]]
-== The new Operations interfaces
-
-In version 3.2 there was the `ElasticsearchOperations` interface that defined all the methods for the `ElasticsearchTemplate` class. In version 4 the functions have been split into different interfaces, aligning these interfaces with the Elasticsearch API:
-
-* `DocumentOperations` are the functions related documents like saving, or deleting
-* `SearchOperations` contains the functions to search in Elasticsearch
-* `IndexOperations` define the functions to operate on indexes, like index creation or mappings creation.
-
-`ElasticsearchOperations` now extends `DocumentOperations` and `SearchOperations` and has methods get access to an `IndexOperations` instance.
-
-NOTE: All the functions from the `ElasticsearchOperations` interface in version 3.2 that are now moved to the `IndexOperations` interface are still available, they are marked as deprecated and have default implementations that delegate to the new implementation:
-
-[source,java]
-----
-/**
- * Create an index for given indexName.
- *
- * @param indexName the name of the index
- * @return {@literal true} if the index was created
- * @deprecated since 4.0, use {@link IndexOperations#create()}

-=== Methods and classes
-
-Many functions and classes have been deprecated. These functions still work, but the Javadocs show with what they should be replaced.
-

-<T> T queryForObject(GetQuery query, Class<T> clazz);
-----
-
-=== Elasticsearch deprecations
-
-Since version 7 the Elasticsearch `TransportClient` is deprecated, it will be removed with Elasticsearch version 8. Spring Data Elasticsearch deprecates the `ElasticsearchTemplate` class which uses the `TransportClient` in version 4.0.
-
-Mapping types were removed from Elasticsearch 7, they still exist as deprecated values in the Spring Data `@Document` annotation and the `IndexCoordinates` class but they are not used anymore internally.
-
-[[elasticsearch-migration-guide-3.2-4.0.removal]]
-== Removals
-
-* As already described, the `ElasticsearchEntityMapper` interface has been removed.
-
-* The `SearchQuery` interface has been merged into it's base interface `Query`, so it's occurrences can just be replaced with `Query`.
-
-* The method `org.springframework.data.elasticsearch.core.ElasticsearchOperations.query(SearchQuery query, ResultsExtractor<T> resultsExtractor);` and the `org.springframework.data.elasticsearch.core.ResultsExtractor` interface have been removed. These could be used to parse the result from Elasticsearch for cases in which the response mapping done with the Jackson based mapper was not enough. Since version 4.0, there are the new <<elasticsearch.operations.searchresulttypes>>  to return the information from an Elasticsearch response, so there is no need to expose this low level functionality.
-
-* The low level methods `startScroll`, `continueScroll` and `clearScroll` have been removed from the `ElasticsearchOperations` interface. For low level scroll API access, there now are `searchScrollStart`, `searchScrollContinue` and `searchScrollClear` methods on the `ElasticsearchRestTemplate` class.

-== Deprecations
-
-.Definition of the id property
-It is possible to define a property of en entity as the id property by naming it either `id` or  `document`.
-This behaviour is now deprecated and will produce a warning.
-PLease us the `@Id` annotation to mark a property as being the id property.
-
-.Index mappings
-In the `ReactiveElasticsearchClient.Indices` interface the `updateMapping` methods are deprecated in favour of the `putMapping` methods.
-They do the same, but `putMapping` is consistent with the naming in the Elasticsearch API:
-
-.Alias handling
-In the `IndexOperations` interface the methods `addAlias(AliasQuery)`, `removeAlias(AliasQuery)` and `queryForAlias()` have been deprecated.
-The new methods `alias(AliasAction)`, `getAliases(String...)` and `getAliasesForIndex(String...)` offer more functionality and a cleaner API.

-.Parent-ID
-Usage of a parent-id has been removed from Elasticsearch since version 6. We now deprecate the corresponding fields and methods.

-== Breaking Changes
-
-=== Return types of ReactiveElasticsearchClient.Indices methods
-
-The methods in the `ReactiveElasticsearchClient.Indices` were not used up to now.
-With the introduction of the `ReactiveIndexOperations` it became necessary to change some of the return types:
-
-* the `createIndex`  variants now return a `Mono<Boolean>` instead of a `Mono<Void>` to signal successful index creation.
-* the `updateMapping`  variants now return a `Mono<Boolean>` instead of a `Mono<Void>` to signal successful mappings storage.
-
-=== Return types of DocumentOperartions.bulkIndex methods
-
-These methods were returing a `List<String>` containing the ids of the new indexed records.
-Now they return a `List<IndexedObjectInformation>`; these objects contain the id and information about optimistic locking (seq_no and primary_term)

-== Breaking Changes
-
-=== RefreshPolicy
-
-==== Enum package changed
-
-It was possible in 4.1 to configure the refresh policy for the `ReactiveElasticsearchTemplate` by overriding the method `AbstractReactiveElasticsearchConfiguration.refreshPolicy()` in a custom configuration class.
-The return value of this method was an instance of the class `org.elasticsearch.action.support.WriteRequest.RefreshPolicy`.
-
-Now the configuration must return `org.springframework.data.elasticsearch.core.RefreshPolicy`.
-This enum has the same values and triggers the same behaviour as before, so only the `import` statement has to be adjusted.
-
-==== Refresh behaviour
-
-`ElasticsearchOperations` and `ReactiveElasticsearchOperations` now explicitly use the `RefreshPolicy` set on the template for write requests if not null.
-If the refresh policy is null, then nothing special is done, so the cluster defaults are used. `ElasticsearchOperations` was always using the cluster default before this version.
-
-The provided implementations for `ElasticsearchRepository` and `ReactiveElasticsearchRepository` will do an explicit refresh when the refresh policy is null.
-This is the same behaviour as in previous versions.
-If a refresh policy is set, then it will be used by the repositories as well.
-
-==== Refresh configuration
-
-When configuring Spring Data Elasticsearch like described in <<elasticsearch.clients>> by using `ElasticsearchConfigurationSupport`, `AbstractElasticsearchConfiguration` or `AbstractReactiveElasticsearchConfiguration` the refresh policy will be initialized to `null`.
-Previously the reactive code initialized this to `IMMEDIATE`, now reactive and non-reactive code show the same behaviour.
-
-=== Method return types
-
-==== delete methods that take a Query
-
-The reactive methods previously returned a `Mono<Long>` with the number of deleted documents, the non reactive versions were void. They now return a `Mono<ByQueryResponse>` which contains much more detailed information about the deleted documents and errors that might have occurred.
-
-==== multiget methods
-
-The implementations of _multiget_ previousl only returned the found entities in a `List<T>` for non-reactive implementations and in a `Flux<T>` for reactive implementations. If the request contained ids that were not found, the information that these are missing was not available. The user needed to compare the returned ids to the requested ones to find
-which ones were missing.
-
-Now the `multiget` methods return a `MultiGetItem` for every requested id. This contains information about failures (like non existing indices) and the information if the item existed (then it is contained in the `MultiGetItem) or not.

-= Elasticsearch Object Mapping
-
-Spring Data Elasticsearch Object Mapping is the process that maps a Java object - the domain entity - into the JSON representation that is stored in Elasticsearch and back.
-
-Earlier versions of Spring Data Elasticsearch used a Jackson based conversion, Spring Data Elasticsearch 3.2.x introduced the <<elasticsearch.mapping.meta-model>>.
-As of version 4.0 only the Meta Object Mapping is used, the Jackson based mapper is not available anymore and the `MappingElasticsearchConverter` is used.
-
-The main reasons for the removal of the Jackson based mapper are:
-
-* Custom mappings of fields needed to be done with annotations like `@JsonFormat` or `@JsonInclude`.
-This often caused problems when the same object was used in different JSON based datastores or sent over a JSON based API.
-* Custom field types and formats also need to be stored into the Elasticsearch index mappings.
-The Jackson based annotations did not fully provide all the information that is necessary to represent the types of Elasticsearch.
-* Fields must be mapped not only when converting from and to entities, but also in query argument, returned data and on other places.
-
-Using the `MappingElasticsearchConverter` now covers all these cases.
-
-[[elasticsearch.mapping.meta-model]]
-== Meta Model Object Mapping
-
-The Metamodel based approach uses domain type information for reading/writing from/to Elasticsearch.
-This allows to register `Converter` instances for specific domain type mapping.
-
-[[elasticsearch.mapping.meta-model.annotations]]
-=== Mapping Annotation Overview
-
-The `MappingElasticsearchConverter` uses metadata to drive the mapping of objects to documents.
-The metadata is taken from the entity's properties which can be annotated.
-
-The following annotations are available:
-
-* `@Document`: Applied at the class level to indicate this class is a candidate for mapping to the database.
-The most important attributes are:
-** `indexName`: the name of the index to store this entity in.
-This can contain a SpEL template expression like `"log-#{T(java.time.LocalDate).now().toString()}"`
-** `type`: [line-through]#the mapping type.
-If not set, the lowercased simple name of the class is used.# (deprecated since version 4.0)
-** `createIndex`: flag whether to create an index on repository bootstrapping.
-Default value is _true_.
-See <<elasticsearch.repositories.autocreation>>
-** `versionType`: Configuration of version management.
-Default value is _EXTERNAL_.
-
-* `@Id`: Applied at the field level to mark the field used for identity purpose.
-* `@Transient`: By default all fields are mapped to the document when it is stored or retrieved, this annotation excludes the field.
-* `@PersistenceConstructor`: Marks a given constructor - even a package protected one - to use when instantiating the object from the database.
-Constructor arguments are mapped by name to the key values in the retrieved Document.
-* `@Field`: Applied at the field level and defines properties of the field, most of the attributes map to the respective https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html[Elasticsearch Mapping] definitions (the following list is not complete, check the annotation Javadoc for a complete reference):
-** `name`: The name of the field as it will be represented in the Elasticsearch document, if not set, the Java field name is used.
-** `type`: The field type, can be one of _Text, Keyword, Long, Integer, Short, Byte, Double, Float, Half_Float, Scaled_Float, Date, Date_Nanos, Boolean, Binary, Integer_Range, Float_Range, Long_Range, Double_Range, Date_Range, Ip_Range, Object, Nested, Ip, TokenCount, Percolator, Flattened, Search_As_You_Type_.
-See https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-types.html[Elasticsearch Mapping Types]
-** `format`: One or more built-in date formats, see the next section <<elasticsearch.mapping.meta-model.date-formats>>.
-** `pattern`: One or more custom date formats, see the next section <<elasticsearch.mapping.meta-model.date-formats>>.
-** `store`: Flag whether the original field value should be store in Elasticsearch, default value is _false_.
-** `analyzer`, `searchAnalyzer`, `normalizer` for specifying custom analyzers and normalizer.
-* `@GeoPoint`: Marks a field as _geo_point_ datatype.
-Can be omitted if the field is an instance of the `GeoPoint` class.
-
-The mapping metadata infrastructure is defined in a separate spring-data-commons project that is technology agnostic.
-
-[[elasticsearch.mapping.meta-model.date-formats]]
-==== Date format mapping
-
-Properties that derive from `TemporalAccessor` or are of type `java.util.Date` must either have a `@Field` annotation
-of type `FieldType.Date` or a custom converter must be registered for this type. This paragraph describes the use of
-`FieldType.Date`.
-
-There are two attributes of the `@Field` annotation that define which date format information is written to the
-mapping (also see https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#built-in-date-formats[Elasticsearch Built In Formats] and https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#custom-date-formats[Elasticsearch Custom Date Formats])
-
-The `format` attributes is used to define at least one of the predefined formats. If it is not defined, then a
-default value of  __date_optional_time_ and _epoch_millis_ is used.
-
-The `pattern` attribute can be used to add additional custom format strings. If you want to use only custom date formats, you must set the `format` property to empty `{}`.
-
-The following table shows the different attributes and the mapping created from their values:
-
-
-[cols=2*,options=header]
-|===
-| annotation
-| format string in Elasticsearch mapping
-
-| @Field(type=FieldType.Date)
-| "date_optional_time\|\|epoch_millis",
-
-| @Field(type=FieldType.Date, format=DateFormat.basic_date)
-| "basic_date"
-
-| @Field(type=FieldType.Date, format={DateFormat.basic_date, DateFormat.basic_time})
-| "basic_date\|\|basic_time"
-
-| @Field(type=FieldType.Date, pattern="dd.MM.uuuu")
-| "date_optional_time\|\|epoch_millis\|\|dd.MM.uuuu",
-
-| @Field(type=FieldType.Date, format={}, pattern="dd.MM.uuuu")
-| "dd.MM.uuuu"
-
-|===
-
-NOTE: If you are using a custom date format, you need to use _uuuu_ for the year instead of _yyyy_.
-This is due to a https://www.elastic.co/guide/en/elasticsearch/reference/current/migrate-to-java-time.html#java-time-migration-incompatible-date-formats[change in Elasticsearch 7].
-
-==== Mapped field names
-
-Without further configuration, Spring Data Elasticsearch will use the property name of an object as field name in Elasticsearch. This can be changed for individual field by using the `@Field` annotation on that property.
-
-It is also possible to define a `FieldNamingStrategy` in the configuration of the client (<<elasticsearch.clients>>). If for example a `SnakeCaseFieldNamingStrategy` is configured, the property _sampleProperty_ of the object would be mapped to _sample_property_ in Elasticsearch. A `FieldNamingStrategy` applies to all entities; it can be overwritten by
-setting a specific name with `@Field` on a property.
-
-[[elasticsearch.mapping.meta-model.rules]]
-=== Mapping Rules
-
-==== Type Hints
-
-Mapping uses _type hints_ embedded in the document sent to the server to allow generic type mapping.
-Those type hints are represented as `_class` attributes within the document and are written for each aggregate root.
-
-.Type Hints
-====
-[source,java]
-----
-public class Person {              <1>
-
-  @Id String id;
-  String firstname;
-  String lastname;
-}

-[source,json]
-----
-{
-  "_class" : "com.example.Person", <1>
-  "id" : "cb7bef",
-  "firstname" : "Sarah",
-  "lastname" : "Connor"
-}
-----
-<1> By default the domain types class name is used for the type hint.
-====
-
-Type hints can be configured to hold custom information.
-Use the `@TypeAlias` annotation to do so.
-
-NOTE: Make sure to add types with `@TypeAlias` to the initial entity set (`AbstractElasticsearchConfiguration#getInitialEntitySet`) to already have entity information available when first reading data from the store.
-
-.Type Hints with Alias
-====
-[source,java]
-----
-@TypeAlias("human")                <1>

-[source,json]
-----
-{
-  "_class" : "human",              <1>
-  "id" : ...
-}
-----
-<1> The configured alias is used when writing the entity.
-====
-
-NOTE: Type hints will not be written for nested Objects unless the properties type is `Object`, an interface or the actual value type does not match the properties declaration.
-
-==== Geospatial Types
-
-Geospatial types like `Point` & `GeoPoint` are converted into _lat/lon_ pairs.

-}
-----
-====
-
-==== GeoJson Types
-
-Spring Data Elasticsearch supports the GeoJson types by providing an interface `GeoJson` and implementations for the different geometries.
-They are mapped to Elasticsearch documents according to the GeoJson specification.
-The corresponding properties of the entity are specified in the index mappings as `geo_shape` when the index mappings is written. (check the https://www.elastic.co/guide/en/elasticsearch/reference/current/geo-shape.html[Elasticsearch documentation] as well)

-= Elasticsearch Operations
-
-Spring Data Elasticsearch uses several interfaces to define the operations that can be called against an Elasticsearch index (for a description of the reactive interfaces see <<elasticsearch.reactive.operations>>).
-
-* `IndexOperations` defines actions on index level like creating or deleting an index.
-* `DocumentOperations` defines actions to store, update and retrieve entities based on their id.
-* `SearchOperations` define the actions to search for multiple entities using queries
-* `ElasticsearchOperations` combines the `DocumentOperations` and `SearchOperations` interfaces.
-
-These interfaces correspond to the structuring of the https://www.elastic.co/guide/en/elasticsearch/reference/current/rest-apis.html[Elasticsearch API].
-
-The default implementations of the interfaces offer:
-
-* index management functionality.
-* Read/Write mapping support for domain types.
-* A rich query and criteria api.
-* Resource management and Exception translation.

-The `IndexOperations` interface and the provided implementation which can be obtained from an `ElasticsearchOperations` instance - for example with a call to `operations.indexOps(clazz)`- give the user the ability to create indices, put mappings or store template and alias information in the Elasticsearch cluster. Details of the index that will be created
-can be set by using the `@Setting` annotation, refer to <<elasticsearc.misc.index.settings>> for further information.
-
-**None of these operations are done automatically** by the implementations of `IndexOperations` or `ElasticsearchOperations`. It is the user's responsibility to call the methods.

-
-[[elasticsearch.operations.searchresulttypes]]
-== Search Result Types
-
-When a document is retrieved with the methods of the  `DocumentOperations` interface, just the found entity will be returned.
-When searching with the methods of the `SearchOperations` interface, additional information is available for each entity, for example the _score_ or the _sortValues_ of the found entity.
-
-In order to return this information, each entity is wrapped in a `SearchHit` object that contains this entity-specific additional information.
-These `SearchHit` objects themselves are returned within a `SearchHits` object which additionally contains informations about the whole search like the _maxScore_ or requested aggregations.
-The following classes and interfaces are now available:
-
-.SearchHit<T>
-Contains the following information:
-
-* Id
-* Score
-* Sort Values
-* Highlight fields
-* Inner hits (this is an embedded `SearchHits` object containing eventually returned inner hits)
-* The retrieved entity of type <T>
-
-.SearchHits<T>
-Contains the following information:
-
-* Number of total hits
-* Total hits relation
-* Maximum score
-* A list of `SearchHit<T>` objects
-* Returned aggregations
-
-.SearchPage<T>
-Defines a Spring Data `Page` that contains a `SearchHits<T>` element and can be used for paging access using repository methods.
-
-.SearchScrollHits<T>
-Returned by the low level scroll API functions in `ElasticsearchRestTemplate`, it enriches a `SearchHits<T>` with the Elasticsearch scroll id.
-
-.SearchHitsIterator<T>
-An Iterator returned by the streaming functions of the `SearchOperations` interface.
-
-[[elasticsearch.operations.queries]]
-== Queries
-
-Almost all of the methods defined in the `SearchOperations` and `ReactiveSearchOperations` interface take a `Query` parameter that defines the query to execute for searching. `Query` is an interface and Spring Data Elasticsearch provides three implementations: `CriteriaQuery`, `StringQuery` and `NativeSearchQuery`.
-
-[[elasticsearch.operations.criteriaquery]]
-=== CriteriaQuery
-
-`CriteriaQuery` based queries allow the creation of queries to search for data without knowing the syntax or basics of Elasticsearch queries. They allow the user to build queries by simply chaining and combining `Criteria` objects that specifiy the criteria the searched documents must fulfill.
-
-NOTE: when talking about AND or OR when combining criteria keep in mind, that in Elasticsearch AND are converted to a **must** condition and OR to a **should**
-
-`Criteria` and their usage are best explained by example
-(let's assume we have a `Book` entity with a `price` property):
-
-.Get books with a given price
-====
-[source,java]
-----
-Criteria criteria = new Criteria("price").is(42.0);
-Query query = new CriteriaQuery(criteria);
-----
-====
-
-Conditions for the same field can be chained, they will be combined with a logical AND:
-
-.Get books with a given price
-====
-[source,java]
-----
-Criteria criteria = new Criteria("price").greaterThan(42.0).lessThan(34.0L);
-Query query = new CriteriaQuery(criteria);
-----
-====
-
-When chaining `Criteria`, by default a AND logic is used:
-
-.Get all persons with first name _James_  and last name _Miller_:
-====
-[source,java]
-----
-Criteria criteria = new Criteria("lastname").is("Miller") <1>
-  .and("firstname").is("James")                           <2>
-Query query = new CriteriaQuery(criteria);
-----
-<1> the first `Criteria`
-<2> the and() creates a new `Criteria` and chaines it to the first one.
-====
-
-If you want to create nested queries, you need to use subqueries for this. Let's assume we want to find all persons with a last name of _Miller_ and a first name of either _Jack_ or _John_:
-
-.Nested subqueries
-====
-[source,java]
-----
-Criteria miller = new Criteria("lastName").is("Miller")  <.>
-  .subCriteria(                                          <.>
-    new Criteria().or("firstName").is("John")            <.>
-      .or("firstName").is("Jack")                        <.>
-  );
-Query query = new CriteriaQuery(criteria);
-----
-<.> create a first `Criteria` for the last name
-<.> this is combined with AND to a subCriteria
-<.> This sub Criteria is an OR combination for the first name _John_
-<.> and the first name Jack
-====
-
-Please refer to the API documentation of the `Criteria` class for a complete overview of the different available operations.
-
-[[elasticsearch.operations.stringquery]]
-=== StringQuery
-
-This class takes an Elasticsearch query as JSON String.
-The following code shows a query that searches for persons having the first name "Jack":
-
-====
-[source,java]
-----
-
-Query query = new SearchQuery("{ \"match\": { \"firstname\": { \"query\": \"Jack\" } } } ");
-SearchHits<Person> searchHits = operations.search(query, Person.class);
-
-----
-====
-
-Using `StringQuery` may be appropriate if you already have an Elasticsearch query to use.
-
-[[elasticsearch.operations.nativesearchquery]]
-=== NativeSearchQuery
-
-`NativeSearchQuery` is the class to use when you have a complex query, or a query that cannot be expressed by using the `Criteria` API, for example when building queries and using aggregates.
-It allows to use all the different `QueryBuilder` implementations from the Elasticsearch library therefore named "native".
-
-The following code shows how to search for persons with a given firstname and for the found documents have a terms aggregation that counts the number of occurences of the lastnames for these persons:
-
-====
-[source,java]
-----
-Query query = new NativeSearchQueryBuilder()
-    .addAggregation(terms("lastnames").field("lastname").size(10)) //
-    .withQuery(QueryBuilders.matchQuery("firstname", firstName))
-    .build();
-
-SearchHits<Person> searchHits = operations.search(query, Person.class);

-=== @Highlight
-
-The `@Highlight` annotation on a repository method defines for which fields of the returned entity highlighting should be included. To search for some text in a `Book` 's name or summary and have the found data highlighted, the following repository method can be used:
-
-====
-[source,java]
-----
-interface BookRepository extends Repository<Book, String> {
-
-    @Highlight(fields = {
-        @HighlightField(name = "name"),

-    })
-    List<SearchHit<Book>> findByNameOrSummary(String text, String summary);
-}
-----
-====
-
-It is possible to define multiple fields to be highlighted like above, and both the `@Highlight` and the `@HighlightField` annotation can further be customized with a `@HighlightParameters` annotation. Check the Javadocs for the possible configuration options.
-
-In the search results the highlight data can be retrieved from the `SearchHit` class.

-[[elasticsearch.routing]]
-= Routing values
-
-When Elasticsearch stores a document in an index that has multiple shards, it determines the shard to you use based on the _id_ of the document.
-Sometimes it is necessary to predefine that multiple documents should be indexed on the same shard (join-types, faster search for related data).
-For this Elasticsearch offers the possibility to define a routing, which is the value that should be used to calculate the shard from instead of the _id_.
-
-Spring Data Elasticsearch supports routing definitions on storing and retrieving data in the following ways:
-
-== Routing on join-types
-
-When using join-types (see <<elasticsearch.jointype>>), Spring Data Elasticsearch will automatically use the `parent` property of the entity's `JoinField` property as the value for the routing.
-
-This is correct for all the use-cases where the parent-child relationship has just one level.
-If it is deeper, like a child-parent-grandparent relationship - like in the above example from _vote_ -> _answer_ -> _question_ - then the routing needs to explicitly specified by using the techniques described in the next section (the _vote_ needs the _question.id_ as routing value).
-
-== Custom routing values
-
-To define a custom routing for an entity, Spring Data Elasticsearch provides a `@Routing` annotation (reusing the `Statement` class from above):
-
-====
-[source,java]
-----
-@Document(indexName = "statements")
-@Routing("routing")                  <.>
-public class Statement {
-    @Id
-    private String id;
-
-    @Field(type = FieldType.Text)
-    private String text;
-
-    @JoinTypeRelations(
-        relations =
-            {
-                @JoinTypeRelation(parent = "question", children = {"answer", "comment"}),
-                @JoinTypeRelation(parent = "answer", children = "vote")
-            }
-    )
-    private JoinField<String> relation;
-
-    @Nullable
-    @Field(type = FieldType.Keyword)
-    private String routing;          <.>
-
-    // getter/setter...
-}
-----
-<.> This defines _"routing"_ as routing specification
-<.> a property with the name _routing_
-====
-
-If the `routing` specification of the annotation is a plain string and not a SpEL expression, it is interpreted as the name of a property of the entity, in the example it's the _routing_ property.
-The value of this property will then be used as the routing value for all requests that use the entity.
-
-It is also possible to us a SpEL expression in the `@Document` annotation like this:
-
-====
-[source,java]
-----
-@Document(indexName = "statements")
-@Routing("@myBean.getRouting(#entity)")
-public class Statement{
-    // all the needed stuff
-}
-----
-====
-
-In this case the user needs to provide a bean with the name _myBean_ that has a method `String getRouting(Object)`. To reference the entity _"#entity"_ must be used in the SpEL expression, and the return value must be `null` or the routing value as a String.
-
-If plain property's names and SpEL expressions are not enough to customize the routing definitions, it is possible to define provide an implementation of the `RoutingResolver` interface. This can then be set on the `ElasticOperations` instance:
-
-====
-[source,java]
-----
-RoutingResolver resolver = ...;
-
-ElasticsearchOperations customOperations= operations.withRouting(resolver);
-
-----
-====
-
-The `withRouting()` functions return a copy of the original `ElasticsearchOperations` instance with the customized routing set.
-
-
-When a routing has been defined on an entity when it is stored in Elasticsearch, the same value must be provided when doing a _get_ or _delete_ operation. For methods that do not use an entity - like `get(ID)` or `delete(ID)` - the `ElasticsearchOperations.withRouting(RoutingResolver)` method can be used like this:
-
-====
-[source,java]
-----
-String id = "someId";
-String routing = "theRoutingValue";
-
-// get an entity
-Statement s = operations
-                .withRouting(RoutingResolver.just(routing))       <.>
-                .get(id, Statement.class);
-
-// delete an entity
-operations.withRouting(RoutingResolver.just(routing)).delete(id);
-
-----
-<.> `RoutingResolver.just(s)` returns a resolver that will just return the given String.

-= Reactive Elasticsearch Operations
-
-`ReactiveElasticsearchOperations` is the gateway to executing high level commands against an Elasticsearch cluster using the `ReactiveElasticsearchClient`.
-
-The `ReactiveElasticsearchTemplate` is the default implementation of `ReactiveElasticsearchOperations`.
-
-[[elasticsearch.reactive.template]]
-== Reactive Elasticsearch Template
-
-To get started the `ReactiveElasticsearchTemplate` needs to know about the actual client to work with.
-Please see <<elasticsearch.clients.reactive>> for details on the client.
-
-[[elasticsearch.reactive.template.configuration]]
-=== Reactive Template Configuration
-
-The easiest way of setting up the `ReactiveElasticsearchTemplate` is via `AbstractReactiveElasticsearchConfiguration` providing
-dedicated configuration method hooks for `base package`, the `initial entity set` etc.
-
-.The AbstractReactiveElasticsearchConfiguration
-====
-[source,java]
-----
-@Configuration
-public class Config extends AbstractReactiveElasticsearchConfiguration {
-
-  @Bean <1>
-  @Override
-  public ReactiveElasticsearchClient reactiveElasticsearchClient() {
-      // ...
-  }
-}
-----
-<1> Configure the client to use. This can be done by `ReactiveRestClients` or directly via `DefaultReactiveElasticsearchClient`.
-====
-
-NOTE: If applicable set default `HttpHeaders` via the `ClientConfiguration` of the `ReactiveElasticsearchClient`. See <<elasticsearch.clients.configuration>>.
-
-TIP: If needed the `ReactiveElasticsearchTemplate` can be configured with default `RefreshPolicy` and `IndicesOptions` that get applied to the related requests by overriding the defaults of `refreshPolicy()` and `indicesOptions()`.
-
-However one might want to be more in control over the actual components and use a more verbose approach.
-
-.Configure the ReactiveElasticsearchTemplate
-====
-[source,java]
-----
-@Configuration
-public class Config {
-
-  @Bean <1>
-  public ReactiveElasticsearchClient reactiveElasticsearchClient() {
-    // ...
-  }
-  @Bean <2>
-  public ElasticsearchConverter elasticsearchConverter() {
-    return new MappingElasticsearchConverter(elasticsearchMappingContext());
-  }
-  @Bean <3>
-  public SimpleElasticsearchMappingContext elasticsearchMappingContext() {
-    return new SimpleElasticsearchMappingContext();
-  }
-  @Bean <4>
-  public ReactiveElasticsearchOperations reactiveElasticsearchOperations() {
-    return new ReactiveElasticsearchTemplate(reactiveElasticsearchClient(), elasticsearchConverter());
-  }
-}
-----
-<1> Configure the client to use. This can be done by `ReactiveRestClients` or directly via `DefaultReactiveElasticsearchClient`.
-<2> Set up the `ElasticsearchConverter` used for domain type mapping utilizing metadata provided by the mapping context.
-<3> The Elasticsearch specific mapping context for domain type metadata.
-<4> The actual template based on the client and conversion infrastructure.
-====
-
-[[elasticsearch.reactive.template.usage]]
-=== Reactive Template Usage
-
-`ReactiveElasticsearchTemplate` lets you save, find and delete your domain objects and map those objects to documents stored in Elasticsearch.
-
-Consider the following:
-
-.Use the ReactiveElasticsearchTemplate
-====
-[source,java]
-----
-@Document(indexName = "marvel")
-public class Person {
-
-  private @Id String id;
-  private String name;
-  private int age;
-  // Getter/Setter omitted...
-}
-----
-
-[source,java]
-----
-template.save(new Person("Bruce Banner", 42))                    <1>
-  .doOnNext(System.out::println)
-  .flatMap(person -> template.findById(person.id, Person.class)) <2>
-  .doOnNext(System.out::println)
-  .flatMap(person -> template.delete(person))                    <3>
-  .doOnNext(System.out::println)
-  .flatMap(id -> template.count(Person.class))                   <4>
-  .doOnNext(System.out::println)
-  .subscribe(); <5>
-----
-
-The above outputs the following sequence on the console.
-
-[source,text]
-----
-> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
-> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
-> QjWCWWcBXiLAnp77ksfR
-> 0
-----
-<1> Insert a new `Person` document into the _marvel_ index under type _characters_. The `id` is generated on server side and set into the instance returned.
-<2> Lookup the `Person` with matching `id` in the _marvel_ index under type _characters_.
-<3> Delete the `Person` with matching `id`, extracted from the given instance, in the _marvel_ index under type _characters_.
-<4> Count the total number of documents in the _marvel_ index under type _characters_.
-<5> Don't forget to _subscribe()_.

-= Reactive Elasticsearch Repositories
-
-Reactive Elasticsearch repository support builds on the core repository support explained in <<repositories>> utilizing
-operations provided via <<elasticsearch.reactive.operations>> executed by a <<elasticsearch.clients.reactive>>.
-
-Spring Data Elasticsearch reactive repository support uses https://projectreactor.io/[Project Reactor] as its reactive
-composition library of choice.
-
-There are 3 main interfaces to be used:
-
-* `ReactiveRepository`
-* `ReactiveCrudRepository`
-* `ReactiveSortingRepository`
-
-[[elasticsearch.reactive.repositories.usage]]
-== Usage
-
-To access domain objects stored in a Elasticsearch using a `Repository`, just create an interface for it.
-Before you can actually go on and do that you will need an entity.
-
-.Sample `Person` entity
-====
-[source,java]
-----
-public class Person {
-
-  @Id
-  private String id;
-  private String firstname;
-  private String lastname;
-  private Address address;
-
-  // … getters and setters omitted
-}
-----
-====
-
-NOTE: Please note that the `id` property needs to be of type `String`.
-
-.Basic repository interface to persist Person entities
-====
-[source]
-----
-interface ReactivePersonRepository extends ReactiveSortingRepository<Person, String> {
-
-  Flux<Person> findByFirstname(String firstname);                                   <1>
-
-  Flux<Person> findByFirstname(Publisher<String> firstname);                        <2>
-
-  Flux<Person> findByFirstnameOrderByLastname(String firstname);                    <3>
-
-  Flux<Person> findByFirstname(String firstname, Sort sort);                        <4>
-
-  Flux<Person> findByFirstname(String firstname, Pageable page);                    <5>
-
-  Mono<Person> findByFirstnameAndLastname(String firstname, String lastname);       <6>
-
-  Mono<Person> findFirstByLastname(String lastname);                                <7>
-
-  @Query("{ \"bool\" : { \"must\" : { \"term\" : { \"lastname\" : \"?0\" } } } }")
-  Flux<Person> findByLastname(String lastname);                                     <8>
-
-  Mono<Long> countByFirstname(String firstname)                                     <9>
-
-  Mono<Boolean> existsByFirstname(String firstname)                                 <10>
-
-  Mono<Long> deleteByFirstname(String firstname)                                    <11>
-}
-----
-<1> The method shows a query for all people with the given `lastname`.
-<2> Finder method awaiting input from `Publisher` to bind parameter value for `firstname`.
-<3> Finder method ordering matching documents by `lastname`.
-<4> Finder method ordering matching documents by the expression defined via the `Sort` parameter.
-<5> Use `Pageable` to pass offset and sorting parameters to the database.
-<6> Finder method concating criteria using `And` / `Or` keywords.
-<7> Find the first matching entity.
-<8> The method shows a query for all people with the given `lastname` looked up by running the annotated `@Query` with given
-parameters.
-<9> Count all entities with matching `firstname`.
-<10> Check if at least one entity with matching `firstname` exists.
-<11> Delete all entites with matching `firstname`.
-====
-
-[[elasticsearch.reactive.repositories.configuration]]
-== Configuration
-
-For Java configuration, use the `@EnableReactiveElasticsearchRepositories` annotation. If no base package is configured,
-the infrastructure scans the package of the annotated configuration class.
-
-The following listing shows how to use Java configuration for a repository:
-
-.Java configuration for repositories
-====
-[source,java]
-----
-@Configuration
-@EnableReactiveElasticsearchRepositories
-public class Config extends AbstractReactiveElasticsearchConfiguration {
-
-  @Override
-  public ReactiveElasticsearchClient reactiveElasticsearchClient() {
-    return ReactiveRestClients.create(ClientConfiguration.localhost());
-  }
-}
-----
-====
-
-Because the repository from the previous example extends `ReactiveSortingRepository`, all CRUD operations are available
-as well as methods for sorted access to the entities. Working with the repository instance is a matter of dependency
-injecting it into a client, as the following example shows:
-
-.Sorted access to Person entities
-====
-[source,java]
-----
-public class PersonRepositoryTests {
-
-  @Autowired ReactivePersonRepository repository;
-
-  @Test
-  public void sortsElementsCorrectly() {
-
-    Flux<Person> persons = repository.findAll(Sort.by(new Order(ASC, "lastname")));
-
-    // ...
-  }
-}
