OK, I searched through how-tos and any other documentation I could find, but I couldn't come up with an answer to this simple question, so I'm afraid I have to turn to the list.

I'm trying to query a ZCatalog for objects where a particular property (which I'm cataloging as a FieldIndex) is not empty. I can't figure out for the life of me what the syntax to do this is :-) I fear this type of query is not forseen:

you can try to emulate the query with a minimum range query and a sufficiently small minimal value. Look at the ZCatalog section in URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html for details. Dieter
