I am trying to build a property seach engine that will search an entire Zope site for a names property .... Have a look at "ZopeFind" and the property API.

"ZopeFind" is the magic behind Zope's "find" support. It can search a complete subtree and return the list of objects satisfying several criteria. The property API allows you to test for a property. I think, you can ask for the list of properties, too. Dieter
