Add test and directly use SearchHit to pass on the index name.
Fix minor flaw in Exception translation for non existing indices along the way.

Fix generics in ElasticsearchEntityMapper. Extract methods. Move enum conversion handling to simple type handling for symmetric implementation. Swap comparison of nullable types to avoid potential null dereference.
Rename ElasticsearchDefaultTypeMapper to DefaultElasticsearchTypeMapper. Move MapTypeAliasAccessor to DefaultElasticsearchTypeMapper.
Introduce SearchResultMapperAdapter to avoid empty method implementations in anonymous classes. Javadoc, reference docs, formatting.

The root cause of the deletion problem was the doScroll which did not apply the given query and therefor returned all entries from the index.
The doScroll implementation has been fixed to apply the query and multiple unit tests have been added to ensure that the delete methods delete the desired documents only and leave the rest untouched.
Also added unit tests for the scrolling to test it against real queries (not only matchAll).

The getMapping methods in the ElasticsearchRestTemplate now behave like the methods in the ElasticsearchTemplate and return the mapping for the specified index and type.

Reactive Elasticsearch repository support builds on the core repository support utilizing
operations provided via ReactiveElasticsearchOperations executed by a ReactiveElasticsearchClient.
Spring Data Elasticsearchs reactive repository support uses Project Reactor as its reactive
composition library of choice.
There are 3 main interfaces to be used:
* ReactiveRepository
* ReactiveCrudRepository
* ReactiveSortingRepository
For Java configuration, use the @EnableReactiveElasticsearchRepositories annotation.
The following listing shows how to use Java configuration for a repository:
@Configuration
@EnableReactiveElasticsearchRepositories
public class Config extends AbstractReactiveElasticsearchConfiguration {
@Override
public ReactiveElasticsearchClient reactiveElasticsearchClient() {
return ReactiveRestClients.create(ClientConfiguration.localhost());
}
}
Using a repository that extends ReactiveSortingRepository makes all CRUD operations 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.
The repository itself allows defining additional methods backed by the inferred proxy.
public interface ReactivePersonRepository extends ReactiveSortingRepository<Person, String> {
Flux<Person> findByFirstname(String firstname);
Flux<Person> findByFirstname(Publisher<String> firstname);
Flux<Person> findByFirstnameOrderByLastname(String firstname);
Flux<Person> findByFirstname(String firstname, Sort sort);
Flux<Person> findByFirstname(String firstname, Pageable page);
Mono<Person> findByFirstnameAndLastname(String firstname, String lastname);
Mono<Person> findFirstByLastname(String lastname);
@Query("{ \"bool\" : { \"must\" : { \"term\" : { \"lastname\" : \"?0\" } } } }")
Flux<Person> findByLastname(String lastname);
Mono<Long> countByFirstname(String firstname)
Mono<Boolean> existsByFirstname(String firstname)
Mono<Long> deleteByFirstname(String firstname)
}

The ReactiveElasticsearchClient now support scrolling through large result sets issuing subsequent _search/scroll requests while emitting data on the outbound channel. Resources bound via their scrollId get freed on completion of the flux.
Original Pull Request: #231
Update documentation to cover newly added configuration options for the ReactiveElasticsearchClient.
Make sure to apply postFilter correctly and set a default limit for unpaged search requests.
Also fix some code format issues.
We now log HTTP requests and responses with the org.springframework.data.elasticsearch.client.WIRE logger for both, the HighLevelRestClient and our reactive client and associate a logging Id for improved traceability.
Configuration of connection/socket timeouts is now available via the ClientConfiguration.
Along the lines we also aligned entity handling to EntityOperations already common in other modules. EntityOperations centralizes how aspects of entities (versioning, retrieval of index name/index type) are handled.

ReactiveElasticsearchOperations is the gateway to executing high level commands against an Elasticsearch cluster using the ReactiveElasticsearchClient.
The ReactiveElasticsearchTemplate is the default implementation of ReactiveElasticsearchOperations and offers the following set of features.
* Read/Write mapping support for domain types.
* A rich query and criteria api.
* Resource management and Exception translation.
To get started the ReactiveElasticsearchTemplate needs to know about the actual client to work with.
The easiest way of setting up the ReactiveElasticsearchTemplate is via AbstractReactiveElasticsearchConfiguration providing
dedicated configuration method hooks for base package, the initial entity set etc.
@Configuration
public class Config extends AbstractReactiveElasticsearchConfiguration {
@Bean
@Override
public ReactiveElasticsearchClient reactiveElasticsearchClient() {
// ...
}
}
NOTE: If applicable set default HttpHeaders via the ClientConfiguration of the ReactiveElasticsearchClient.
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().
The ReactiveElasticsearchTemplate lets you save, find and delete your domain objects and map those objects to documents stored in Elasticsearch.
@Document(indexName = "marvel", type = "characters")
public class Person {
private @Id String id;
private String name;
private int age;
// Getter/Setter omitted...
}
template.save(new Person("Bruce Banner", 42)) // save a new document
.doOnNext(System.out::println)
.flatMap(person -> template.findById(person.id, Person.class)) // then go find it
.doOnNext(System.out::println)
.flatMap(person -> template.delete(person)) // just to remove remove it again
.doOnNext(System.out::println)
.flatMap(id -> template.count(Person.class)) // so we've got nothing at the end
.doOnNext(System.out::println)
.subscribe(); // yeah :)
The above outputs the following sequence on the console.
> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> QjWCWWcBXiLAnp77ksfR
> 0

Convert spaces to tabs for pom.xml. Switch reactive dependencies to optional. Remove unused commonscollections property. Use managed versions for reactor and Spring dependencies.
Introduce WebClientProvider to avoid reinstantiation of WebClient instances. Introduce ClientConfiguration to encapsulate common Elasticsearch client configuration properties. Split ElasticsearchClients into RestClients and ReactiveRestClients to avoid mandatory dependency on WebFlux/Project Reactor. Adapt tests and code referring to WebClient creation.
Extract response body as byte array instead of Flux of DataBuffer to avoid chunking and to parse an entire response.
Encapsulate hostAndPort string used across configuration/HostProvider with InetSocketAddress. Add parser for InetSocketAddress.

Initial implementation of a ReactiveElasticsearchClient using WebClient to connect to cluster nodes.
ReactiveElasticsearchClient client = ElasticsearchClients.createClient()
.connectedTo("http://localhost:9200", "http://localhost:9201")
.reactive();
A HostProvider selects active nodes and routes requests.
client.index(request ->
request.index("spring-data")
.type("elasticsearch")
.id(randomUUID().toString())
.source(singletonMap("feature", "reactive-client"))
.setRefreshPolicy(IMMEDIATE);
);
This implementation provides the first building block for reactive Template and Repository support to be added subsequently.
Along the lines we upgraded to Elasticsearch 6.5.

* Move @Parent property recognition to ElasticsearchPersistentProperty
* Move type contraints for @Version and @Parent fields to ElasticsearchPersistentProperty to fail faster
* remove unused constant SUPPORTED_ID_TYPES from SimpleElasticsearchPersistentProperty
Original pull request: #208
Extracted ClusterNodes value object to capture the parsing logic and actually properly test it. Added unit tests to verify the proper rejection and the two cases outlined in the ticket.
Related tickets: DATAES-283.
SimpleElasticsearchPersistentProperty now already checks for the correct type of score properties. Added unit tests for that. Also added unit tests for SimpleElasticsearchPersistentEntity rejecting more than one score property being present.
Additional non-null assertions on components that are required so that we can remove superfluous null checks.
A bit o formatting, Javadoc, missing @since tags and license headers.
Original pull request: #207.
* drop superfluous class FieldIndex
* change FieldType text and keyword starting with capital letters
