[Zope] Catalog problems

[John Goerzen]

OK, here's the situation.  I want to build a search engine that
applies to a particular folder and all its sub-folders.  I want this
search engine to be a FULL TEXT one, meaning it will need to search
through the body text of documents.

I have been unable to figure out how to set this up with catalogs.  Do 
any of you have some pointers to help me out?  Specifically, I can't
figure out how to limit it to one particular folder, and how to tell
it to do a full text index.
