I'm using Zope-2.6.1 with ZCatalog and several Keyword indexes. How can I make a query on a KeywordIndex to get objects for which a given value is not found ??
Not easily :-/
The underlying BTrees support this but ZCatalog's engine for combing them is pretty rigid. I think Casey did some work on breaking this apart recently, maybe he can help?
Here is a recipe I wrote for this a while back: http://www.zopelabs.com/cookbook/1015785843/1026625784 hth, -Casey
