PAB wants to combine the simple search (which is actually very complicated behind the scenes, since it does keyword lookups and combines them with supplementary text-searching) with the advanced search filters. This is proving virtually impossible, partly because it's just too messy -- you'd need to retrieve a document set from the keyword search in a separate step, and then filter it -- and partly because I just don't have time to implement it properly before the launch. I'll have a couple more shots at it, but things aren't looking good so far.

Made a few other changes and fixes requested with PAB, and hid the text search box, since it's doing what it says on the box (a text search), and not what PAB wants (a complicated keyword search).
