Method Detail

createFullTextQuery

FullTextQuery createFullTextQuery(org.apache.lucene.search.Query luceneQuery,
                                  Class<?>... entities)

Create a fulltext query on top of a native Lucene query returning the matching objects of type entities and their respective subclasses.

Parameters:

luceneQuery - The native Lucene query to be rn against the Lucene index.

entities - List of classes for type filtering. The query result will only return entities of the specified types and their respective subtype. If no class is specified no type filtering will take place.

Returns:

A FullTextQuery wrapping around the native Lucene wuery.

Throws:

IllegalArgumentException - if entityType is null or not a class or superclass annotated with @Indexed.

createFullTextQuery

FullTextQuery createFullTextQuery(org.hibernate.search.query.engine.spi.QueryDescriptor descriptor,
                                  Class<?>... entities)

Creates a fulltext query from the given query descriptor.

Parameters:

descriptor - The query descriptor

entities - List of classes for type filtering. The query result will only return entities of the specified types and their respective subtype. If no class is specified no type filtering will take place.

Returns:

A FullTextQuery using the given query descriptor.

Throws:

IllegalArgumentException - if entityType is null or not a class or superclass annotated with @Indexed.

index

<T> void index(T entity)

Force the (re)indexing of a given managed object. Indexation is batched per transaction: if a transaction is active, the operation will not affect the index at least until commit.

Any EntityIndexingInterceptor registered on the entity will be ignored: this method forces an index operation.

Type Parameters:

T - the type of the entity to index

Parameters:

entity - The entity to index - must not be null.

Throws:

IllegalArgumentException - if entity is null or not an @Indexed entity

getSearchFactory

SearchFactory getSearchFactory()

Returns:

the SearchFactory instance.

purge

<T> void purge(Class<T> entityType,
               Serializable id)

Remove the entity with the type entityType and the identifier id from the index. If id == null all indexed entities of this type and its indexed subclasses are deleted. In this case this method behaves like purgeAll(Class).

Any EntityIndexingInterceptor registered on the entity will be ignored: this method forces a purge operation.

Type Parameters:

T - the type of the entity to purge

Parameters:

entityType - The type of the entity to delete.

id - The id of the entity to delete.

Throws:

IllegalArgumentException - if entityType is null or not a class or superclass annotated with @Indexed.

purgeAll

<T> void purgeAll(Class<T> entityType)

Remove all entities from of particular class and all its subclasses from the index.

Any EntityIndexingInterceptor registered on the entity type will be ignored.

Type Parameters:

T - the type of the entity to purge

Parameters:

entityType - The class of the entities to remove.

Throws:

IllegalArgumentException - if entityType is null or not a class or superclass annotated with @Indexed.

flushToIndexes

void flushToIndexes()

Flush all index changes forcing Hibernate Search to apply all changes to the index not waiting for the batch limit.

createIndexer

MassIndexer createIndexer(Class<?>... types)

Creates a MassIndexer to rebuild the indexes of some or all indexed entity types. Instances cannot be reused.

Any EntityIndexingInterceptor registered on the entity types are applied: each instance will trigger an EntityIndexingInterceptor.onAdd(Object) event from where you can customize the indexing operation.

Parameters:

types - optionally restrict the operation to selected types

Returns:

a new MassIndexer
