Actually I have heard of open source search server; I have to admit I've not played with it much, but it looks like a nice clean implementation. the concept looks very cool. I especially like the SAAS that you provide!

You should add Terrier - open source enterprise search engine

Terrier is a highly flexible, efficient, effective, and robust search engine, readily deployable on large-scale collections of documents.

Thanks for mentioning Xapian and Flax, but just to clarify, both of these are GPL-licensed and entirely open source.

Thanks, Charlie, for correcting us!
