[Zope] ZCatalog & dynamic sites

Hi all, I have a Zope site that uses MySQL to dynamically create some pages. What I want is the ability to search throughout the site, INCLUDING the pages that are database-driven. It seems to me that ZCatalog only finds items that exist *in zope*. Is it something ZCatalog can't do or am I missing anything obvious ? -- Dimitris http://atlas.central.ntua.gr:8000/~mc94068
