I wrote an extremely basic search using postgres full text search (documented here http://tech.pro/tutorial/1142/building-faceted-search-with-postgresql http://tech.pro/tutorial/1142/building-faceted-search-with-p...) that was very easy to get up and running. It got us pretty much 95% there for a usable product search for the ecommerce site I was on at the time. While it might be limited for full blown search; it does pretty damn well for handling english language search of product descriptions, labels, and any other categorization. I would definitely recommend it if you need a fast solution that is easy to implement (and doesn't really incur much tech debt) so you can get back to working on things that might matter more to your particular project.
