Doh.  I will (I mean Ken will) have that up and running today.

Oh man, I knew someone would open up the Query Language can of worms.
Yep, your right, the catalog (like ZTables) takes only the intersection
of a search.  Modifying the _indexedSearch() algorithm wouldn't be too
hard, it's just *how* to modify it is the tricky part.  The ideal
solution would be to create some sort of query language that web form
could dynamicly build queries to, that way, you can design your querty
rather smartly.  A nifty wizard could even be built to build complex web
forms that you can then tweak for usability.  Brainstorm on this, and
let me know what you come up with.

Thanks, today I'm doing some general cleanup on the code.  I'll wack it.
