I had a very similar need for legal terms (e.g., "power of
attorney") and the thesaurus fit that need exactly.

I don't know whether you'll run into the other need I had that
required some special handling for full text search with legal
documents: things like dates, case numbers, and statute cites were
not handled well by default. What I did there was to pick those
out with regular expression searches, put them into a
space-separated string, cast that to tsvector, assign a higher
weight to such key elements, and concatenate that tsvector with the
one generated from the standard text parser and dictionaries.
