Hibernate Search

Description

Hibernate Search automatically extracts data from Hibernate ORM entities to push it to local Apache Lucene indexes or remote Elasticsearch/OpenSearch indexes.

It features:

Declarative mapping of entity properties to index fields, either through annotations or a programmatic API.
On-demand mass indexing of all entities in the database, to initialize the indexes with pre-existing data.
On-the-fly listener-triggered indexing of entities modified through a Hibernate ORM session, to always keep the indexes up-to-date.
A Search DSL to easily build full-text search queries and retrieve the hits as Hibernate ORM entities.
And more: configuration of analyzers, many different predicates and sorts in the Search DSL, spatial support. search queries returning projections instead of entities, aggregations, advanced customization of the mapping using bridges, ...

For example, map your entities like this:

@Entity
// This entity is mapped to an index
@Indexed
public class Book {

    // The entity ID is the document ID
    @Id
    @GeneratedValue
    private Integer id;

    // This property is mapped to a document field
    @FullTextField
    private String title;

    @ManyToMany
    // Authors will be embedded in Book documents
    @IndexedEmbedded
    private Set<Author> authors = new HashSet<>();

    // Getters and setters
    // ...
}

@Entity
public class Author {

    @Id
    @GeneratedValue
    private Integer id;

    // This property is mapped to a document field
    @FullTextField
    private String name;

    @ManyToMany(mappedBy = "authors")
    private Set<Book> books = new HashSet<>();

    // Getters and setters
    // ...
}

Index existing data like this:

SearchSession searchSession = Search.session( entityManager );
MassIndexer indexer = searchSession.massIndexer( Book.class );
indexer.startAndWait();

Listener-triggered indexing does not require any change to code based on JPA or Hibernate ORM:

Author author = new Author();
author.setName( "Isaac Asimov" );

Book book = new Book();
book.setTitle( "The Caves Of Steel" );
book.getAuthors().add( author );
author.getBooks().add( book );

entityManager.persist( author );
entityManager.persist( book );

And search like this:

SearchResult<Book> result = Search.session( entityManager )
        .search( Book.class )
        .where( f -> f.match()
                .fields( "title", "authors.name" )
                .matching( "Isaac" ) )
        .fetch( 20 );

List<Book> hits = result.hits();
long totalHitCount = result.total().hitCount();
