Jukka Zitting commented on JCR-2715:
------------------------------------
Yes, I'm still working on fixing some remaining issues before I plug the new
implementation in as the QueryObjectModelImpl.execute() method. I also have
some pending work on tighter integrating the new join query code with the
underlying Lucene index so we can avoid the extra layer of SQL1 queries that
the implementation now uses.
For now it's possible to use this implementation by directly instantiating the
QueryEngine class like this:
QueryObjectModel qom = ...;
QueryResult result = new QueryEngine(session).execute(
qom.getColumns(), qom.getSource(),
qom.getConstraint(), qom.getOrderings());
