[Zope] Simple ZCatalog Question

[James W. Howe]

If I have an object with a boolean property and I want to find all objects 
in my catalog which do *not* have this property, how do I formulate the 
catalog search parameters?  I've tried:

Catalog(meta_type='something', booleanProperty='false')

and

Catalog(meta_type='something', booleanProperty=0)

and a couple of other variations.  Any help would be appreciated.

Thanks.
