org.hibernate.search.FullTextSession.createFullTextQuery()
Create a fulltext query on top of a native Lucene query returning the matching objects of type entities and their respective subclasses. @param luceneQuery The native Lucene query to be rn against the Lucene index. @param entities List of classes for type filtering. The query result will only return entities ofthe specified types and their respective subtype. If no class is specified no type filtering will take place. @return A FullTextQuery wrapping around the native Lucene wuery.
