Class FullTextQueryImpl

java.lang.Object
  org.hibernate.search.jpa.impl.FullTextQueryImpl

All Implemented Interfaces:

javax.persistence.Query, FullTextQuery, ProjectionConstants

public class FullTextQueryImpl
extends Object
implements FullTextQuery

Implements JPA 2 query interface and delegate the call to a Hibernate Core FullTextQuery. This has the consequence of "duplicating" the JPA 2 query logic in some areas.

Constructor Detail

FullTextQueryImpl

public FullTextQueryImpl(FullTextQuery query,
                         Session session)

Method Detail

setSort

public FullTextQuery setSort(org.apache.lucene.search.Sort sort)

Description copied from interface: FullTextQuery

Allows to let lucene sort the results. This is useful when you have additional sort requirements on top of the default lucene ranking. Without lucene sorting you would have to retrieve the full result set and order the hibernate objects.

Specified by:

setSort in interface FullTextQuery

Parameters:

sort - The lucene sort object.

Returns:

this for method chaining

setFilter

public FullTextQuery setFilter(org.apache.lucene.search.Filter filter)

Description copied from interface: FullTextQuery

Allows to use lucene filters. Semi-deprecated? a preferred way is to use the @FullTextFilterDef approach

Specified by:

setFilter in interface FullTextQuery

Parameters:

filter - The lucene filter.

Returns:

this for method chaining

getResultSize

public int getResultSize()

Description copied from interface: FullTextQuery

Returns the number of hits for this search Caution: The number of results might be slightly different from getResultList().size() because getResultList() may be not in sync with the database at the time of query.

Specified by:

getResultSize in interface FullTextQuery

setCriteriaQuery

public FullTextQuery setCriteriaQuery(Criteria criteria)

Description copied from interface: FullTextQuery

Defines the Database Query used to load the Lucene results. Useful to load a given object graph by refining the fetch modes No projection (criteria.setProjection() ) allowed, the root entity must be the only returned type No where restriction can be defined either.

Specified by:

setCriteriaQuery in interface FullTextQuery

setProjection

public FullTextQuery setProjection(String... fields)

Description copied from interface: FullTextQuery

Defines the Lucene field names projected and returned in a query result Each field is converted back to it's object representation, an Object[] being returned for each "row" (similar to an HQL or a Criteria API projection). A projectable field must be stored in the Lucene index and use a TwoWayFieldBridge Unless notified in their JavaDoc, all built-in bridges are two-way. All @DocumentId fields are projectable by design. If the projected field is not a projectable field, null is returned in the object[]

Specified by:

setProjection in interface FullTextQuery

enableFullTextFilter

public FullTextFilter enableFullTextFilter(String name)

Description copied from interface: FullTextQuery

Enable a given filter by its name. Returns a FullTextFilter object that allows filter parameter injection

Specified by:

enableFullTextFilter in interface FullTextQuery

disableFullTextFilter

public void disableFullTextFilter(String name)

Description copied from interface: FullTextQuery

Disable a given filter by its name

Specified by:

disableFullTextFilter in interface FullTextQuery

explain

public org.apache.lucene.search.Explanation explain(int documentId)

Description copied from interface: FullTextQuery

Return the Lucene Explanation object describing the score computation for the matching object/document in the current query

Specified by:

explain in interface FullTextQuery

Parameters:

documentId - Lucene Document id to be explain. This is NOT the object id

Returns:

Lucene Explanation

limitExecutionTimeTo

public FullTextQuery limitExecutionTimeTo(long timeout,
                                          TimeUnit timeUnit)

Description copied from interface: FullTextQuery

*Experimental* API, subject to change or removal Limit the time used by Hibernate Search to execute the query. When the limit is reached, results already fetched are returned. This time limit is a best effort. The query will likely run for longer than the provided time. The time limit only applies to the interactions between Hibernate Search and Lucene. In other words, a query to the database will not be limited. If the limit is reached and all results are not yet fetched, FullTextQuery.hasPartialResults() returns true.

Specified by:

limitExecutionTimeTo in interface FullTextQuery

Parameters:

timeout - time out period

timeUnit - time out unit

hasPartialResults

public boolean hasPartialResults()

Description copied from interface: FullTextQuery

*Experimental* API, subject to change or removal When using FullTextQuery.limitExecutionTimeTo(long, java.util.concurrent.TimeUnit) }, returns true if partial results are returned (ie if the time limit has been reached and the result fetching process has been terminated.

Specified by:

hasPartialResults in interface FullTextQuery

initializeObjectsWith

public FullTextQuery initializeObjectsWith(ObjectLookupMethod lookupMethod,
                                           DatabaseRetrievalMethod retrievalMethod)

Description copied from interface: FullTextQuery

Refine the strategies used to load entities. The lookup method defines whether or not to lookup first in the second level cache or the persistence context before trying to initialize objects from the database. Defaults to SKIP. The database retrieval method defines how objects are loaded from the database. Defaults to QUERY. Note that Hibernate Search can deviate from these choices when it makes sense.

initializeObjectsWith in interface FullTextQuery
