Examples of org.hibernate.search.FullTextQuery.initializeObjectsWith()

org.hibernate.search.FullTextQuery.initializeObjectsWith()
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.

    FullTextQuery fullTextQuery = fullTextSession.createFullTextQuery( parsingResult.getQuery(), parsingResult.getTargetEntity() );
    fullTextQuery.setProjection( parsingResult.getProjections().toArray( new String[parsingResult.getProjections().size()] ) );


    // Following options are mandatory to load matching entities without using a query
    // (chicken and egg problem)
    fullTextQuery.initializeObjectsWith( ObjectLookupMethod.SKIP, DatabaseRetrievalMethod.FIND_BY_ID );
    return fullTextQuery;
  }


  private LuceneProcessingChain createProcessingChain(Session session, Map<String, Object> namedParameters, FullTextSession fullTextSession) {
    EntityNamesResolver entityNamesResolver = getDefinedEntityNames( session.getSessionFactory() );
