java.lang.Object

org.apache.jackrabbit.core.query.lucene.LuceneQueryFactory

org.apache.jackrabbit.core.query.lucene.JahiaLuceneQueryFactoryImpl

public class JahiaLuceneQueryFactoryImpl
extends org.apache.jackrabbit.core.query.lucene.LuceneQueryFactory

Override LuceneQueryFactory - optimize descendantNode constraint (use index) - optimize childNode constraint (use index) - handles rep:facet when executing (todo : might handle that in a constraint, as rep:filter ?) - handles rep:filter in fulltext constraint

isAclUuidInIndex

public boolean isAclUuidInIndex()

Returns true if ACL-UUID should be resolved and stored in index. This can have a negative effect on performance, when setting rights on a node, which has a large subtree using the same rights, as all these nodes will need to be reindexed. On the other side the advantage is that the queries are faster, as the user rights are resolved faster.

Returns:

Returns true if ACL-UUID should be resolved and stored in index.
