I think it has changed for FieldIndexes. You can now make the distinction
between "doesnt have that attribute" and "attribute is one of [None, '', ,
()]" within a Field Index. You do this in an almost natural way, the major
exception being that you need to wrap a blank string ('') in a sequence in
the query (e.g. title=['']) due to hysterical behavior.
I'm not sure about Text Indexes.

I was always very pleased with that characteristic, but I had not
realised it was a design goal.
I thought I observed that characteristic had changed in a recent Zope
release... hmmm, Ill take a look.
