[Zope] Novice Question: Text search of DTML Documents and Methods?

Hi Everyone, I've just started working with Zope, and it seems I've had a bit of bad timing with the moving of the documentation and stuff on the new web-site; I'm having trouble finding stuff. So my apologies if the answers I'm looking for are right under my nose somewhere. ;-) Is there some documented way of searching the contents of Zope Folders and Documents? And if so, can one search within properties as well? And if not, where would be the best place to start for implementing this? Many thanks, Joe
