There's currently no way to do this in a single query, but you can do (inefficient/torturous): unique_states = catalog.uniqueValuesFor('state') l = [] for state in unique_states: if state != 'California': l.append(state) notCalifornia = catalog.searchResults({'state':l}) There is a proposal in the fishbowl that, implemented properly, would provide a difference function that would allow you to do this more efficiently (http://dev.zope.org/Wikis/DevSite/Proposals/UnionAndIntersectionOperations).

I'm probably overlooking this, but has a NOT usage been implemented in fieldIndexes. I would like to have something like
catalog.searchResults({'state':'California','state_usage':'not'})
return a list of everything that did not have "California" as the value for state.
