Introduction to Search with Sphinx

This is an engaging short introduction to Sphinx. At 146 pages, you shouldn’t expect it to go into every detail, and it doesn’t. There are major topics that it omits entirely or mentions only tangentially, such as distributed searching across a cluster of machines,

The Sphinx project just released version 0.9.8, with many enhancements since the previous release. There’s never been a better time to try it out. It’s really cool technology.

What is Sphinx? Glad you asked. It’s fast, efficient, scalable, relevant full-text searching and a heck of a lot more. In fact, Sphinx complements MySQL for a lot of non-search queries that MySQL frankly isn’t very good at, including WHERE clauses on low-selectivity columns, ORDER BY with a LIMIT and OFFSET, and GROUP BY. A lot of you are probably running fairly simple queries with these constructs and getting really bad performance in MySQL. I see it a lot when I’m working with clients, and there’s often not much room for optimization. Sphinx can execute a subset of such queries very efficiently, due to its smart I/O

It's been a while since I said anything about the progress on the book. That doesn't mean we are not still working on it, though.

As Peter wrote a while ago, he is basically wearing the hat of a very advanced technical reviewer at this point. We've finished writing all the chapters from his detailed outlines. He has worked through about half the chapters, and I'm continuing to spend my evenings and weekends and holidays (yes, nearly all my free time -- just ask my wife!) writing some new material (an appendix on EXPLAIN, for example), finishing unfinished things marked with TODO in the text, and revising chapters after Peter reviews them. Vadim is working on benchmarks. For example, he just finished some benchmarks for
