Lucene in Action

Jarkarta is a high-performance, full-featured, java, open-source, text search engine API written by Doug Cutting.
Note that Lucene is specifically an API, not an application. This means that all the hard parts have been done, but the easy programming has been left to you. The payoff for you is that, unlike normal search engine applications, you spend less time wading through tons of options and build a search application that is specifically suited to what you're doing. You can easily develop a custom search application, perfectly suited to your needs. Lucene is startlingly easy to develop with and use.
I'm going to assume that you're a basically competent programmer and that you are basically competent in java.
