[Zope] Help with Search in Zope

Hi I am a newbie to Zope and have been trying to get ZCatalogs to work with indexing my postgres data to be avaiable for search within my site. I have no clues on how this is possible (if possible at all?). I am able to follow the examples on the site to have the search working on the DTML documents etc. But I want to be able to search my database content. Can any one guide me on this please ?
