Search Engine for website

Are there any good free apps, or cheap shareware that I could use... I'd like to integrate a search engine into a relatively small site I'm working on.

phpdig (http://www.phpdig.net/index.php). Be aware though that the only support you're likely to get is from searching their forum. There isn't very much active participation in their forum these days. Still, it's a pretty easy search engine to setup and administer, provided you read the documentation prior to doing so.

sphider is a light weight search engine which can handle upto 1gb database (tested) i havn't run anymore than 50 000 links indexed but it runs pretty fast. indexing service works well.
