Nick,
FOr now, I'd suggest using the fully tested serch package on oacs-5-2 branch. I'll be fixing the version in HEAD. HEAD means, in progress, broken, experimental. There are new features that should be very useful in the HEAD version that are being tested for a specific client right now. I'll try to spend a day fixing the HEAD version, I doubt it actually works on PostgreSQL at the moment without the dotlrn code.
