Is google hiring or is this a source forge project?
That's a lot of work and technique that would either need to become opensource, or it's going to end up as proprietary.
I do wish you luck, however.
EDIT: One additional thing. The Google interface is a combination of front end and back end integration along with, afaik, local cached recent search terms used to clean up incorrect search queries.
It's not just a matter of cleaning up Full Text Searching. Google's entire primary purpose IS searching data, and only that. It's organized around it, optimized for it, and is coded to that purpose. Everything else is an 'extra'.
Never stop learning, even if it hurts. Ego bruises are practically mandatory as you learn unless you've never risked enough to make a mistake.
