Hi,

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 ??

Typically, each of my objects is identified by a globally unique ID (OID) ; an object can keep a reference to another object through an "oid_refs" property (a list), which is indexed in a keyword index. What I want is to be able to find, for example, objects of a given meta-type, eventually stored in a given folder, which are NOT referenced by other objects.

Thanks for any help,

Thierry
