No. The index for Xapian is built in addition via a trigger (see
You can always get back the internal search by disabling the
Search::Xapian plugin (or changing it's 'q' value to 0).

Only Simple search at the moment. The advanced search requires some
things that Xapian can't do e.g. "userid.username".

If you're Xapian is active you will have a "relevance" ordering
available on the search results.

If "title:Term" works then that's the problem.
