Superb interface for searching. Quickly sort results by type, date, etc. and the preview window is what a truly useful search tool must have. It would be nice to have instant indexing, but foxtrot indexing is fast even if you do it manually and painless if you leave your computer on and have done automatically at 4 am.

Release notes for 1.09 should warn you to add ~/Library/Caches/Metadata to locations to be indexed if you want your Entourage messages to be indexed properly.
