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:

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();
