Postgres FTS with trigrams (pg_trigram extension) works really well for many search applications. Most of the effort would be tuning the FTS dictionary.

My issue with it is that a small term such as one word doesn't event match to a record which is weird, I'm using it with rails. Thinking of using elastic search to help with that
