[Zope] ZCatalog Searching on Path

I would like to be able to search a ZCatalog based on the path to the cataloged object. Basically I would like to say "Show me all of the cataloged objects that fall within this folder" and have it return a list. Since the ZCatalog uses the physical path to identify objects I know the data is stored, but has anyone found a way to search on that data? --Brian
