Are you searching against textindexes or fileindexes? Are you sure the values exist in the same zclass instance?

the Catalog isn't a method ...is a callable object , the object you placed on the zope tree.

Searching with the zcatalog isn't ever so obvius..

Some sources of information:


A well done how-to that has been written for dtml but the explained tecniques to call the catalog are the same in  python.
