How do I build a great keyword search engine?

I'm building a small keyword-relevancy search engine. I'd like to move beyond simply keeping track of what words are in what documents -- at least, I assume there's a beyond having to do with keyword density and such. What should I read to find out more? Are the open source projects I should check out?

Apache's Lucene looks to be a pretty capable engine.
