Free Search Engines in PHP?

[purbeast0]

Before I go and write a search engine for my website, I was wondering if there are any freeware search engines out there.

Basically what I need is for it to search the search phrase versus 2 tables in my db. I could probably write one in a somewhat not too complicated fashion, but I'm sure if there are ones out there that have been tweaked and what not it would be more efficient to use one.

Are there any that people recommend? I want to be able to easily integrate this into my own website as well, so that'll help if it's possible. Thanks.

Well, there's lots of stuff out there that will search by scraping your rendered pages but I don't think there can really be a preexisting one that mines your database because nobody else knows what your database schema is.
