Thanks to everone who has given me suggestions on this. I really do appreciate it. After looking over the PTK snapshot, I've tried to duplicate the catlog that is implemented there. I could not find any search utilities built in, so I'm assuming this is still done by adding the ZsearchInterface from the management screen. Is this right, or is there some built-in PTK searching tool? So now I have a "myproductcatalog" class which inherits ZCatalog. All it does is set up the Indexes, and columns In my base class, I initialize the catalog using (PTK code): # Install MyCatalog id = 'SiteIndex' catalog = MyCatalog(id, '') self._setObject(id, catalog) catalog = self.SiteIndex catalog.initialize() My sub-classes are all catalog aware, with reindex-object in all of the editing areas. I don't see my catalog when I go to add a Zsearch interface. Am I supposed to? What else do I need to do to make this work? -ed-
