[Zope] ZCatalog problems

[Jay, Dylan]

As I understand it searching on multiple indexes gives me results that match
the criterea for both indexes. How do I get a result set that has results in
either index, ie Index1="blah" OR Index2="blah" instead of Index1="blah" AND
Index2="blah".

Also I havn't a clue on how catalog a document that is based on a SQL query.
Before I can index my site I need to have this information in my index. Has
anyone been able to do this?
