You need to manually do unions or intersections on results from multiple calls to searchRequest currently.
Is this a feature to be implemented? If not, why not?
DC has no no concrete plans to implement operators or precedence in catalog queries, although I think it's a really super-worthwhile idea. We're currently focusing on the things in the Zope 2.4 plan (see http://dev.zope.org/Resources/zope_240_plan.html). If someone wanted to try to implement it, they could create a fishbowl project and I can provide assistance.
Oh, and by the way, "searchRequest"?
__call__ works too. ;-)

This is a project I have been keeping in the back of my mind for a while now. At present I do not have the resources to devote, but it is my hope that this will change. I feel strongly that that ZCatalog should have a general query language on par with an SQL where clause. Much of the work to implement this exists in various places, it really just needs fleshing out and tying together. I have also been waiting for the ZCatalog changes that have just taken place in 2.3.1. Now that this has happened, it may be a good time to start the discussion in the Fishbowl. I would be willing to draft this proposal, but it will be a few weeks before I realistically can do it. -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
