[Zope] Can't make an AdvancedQuery with NOT

9 Feb 2005

      I just installed AdvancedQuery 0.6 in my Plone site, as it seems to be 
the only way to do boolean search expressions.

Here's the query I'm trying to make:

	query = Eq('Title','kitchen') & - Eq('Subject','deck')

The idea, obviously, is to get all docs with keywords of "kitchen" AND 
NOT "deck"

I'm getting this as an error:

	AttributeError: Eq instance has no attribute '__neg__'

This query works as expected:

	query = Eq('Subject','kitchen') & Eq('Subject','deck')

Installation details:
	Plone 2.0.5
	Zope 2.7.3-0, python 2.3.4, darwin
	AdvancedQuery 0.6
	No IncrementalSearch
	No ManagableIndex

Any ideas?
