Hej, hej! I want to do a search with a ZCatalog, and there are some ANDs and ORs needed. Can I implement them in dtml or do I need to write that in Python? In the Zope tutorial, the only described way is a Python example. Is it possible to say something like <dtml-in expr="Catalog(['topic','old'] or ['region','east'])"> or are all ORs and ANDs bound to Python? Thanx a lot in advance!
