spot on. OP: Are you asking how basic tf-idf works, or is there something you can't get lucene / SOLR / sphinx / tsearch to do easily?

nevertheless, here are some good background materials (search amazon on "data mining"

Also the Collective intelligence by Satnam alag is quite good (a lot of java code to wade through tho

To be honest I hadn't even heard of tf-idf before you mentioned it. It is definitely not the case I am stepping beyond the bounds of something like sphinx.

I basically want to lay a bit of foundation before I start mucking around with something I have no idea about.

I have a couple e-books on Data Mining but I didn't think it was applicable. Are Data Mining and Search two things closely intertwined?
