I am not searching from a form in that sense...I am talking about at the python

I have self.searchResults({'description':'blah'})  where description is meta
data in the catalog and a textindex and 'blah' is in the Vocabulary.  This
previously worked in zope2.1.6.  Now in 2.2.0 and 2.2.1 it doesn't work.  The
only thing way I can get searchResults() to return a non empty list is to search
using a Field index and a valid string to match with.
