Have you looked at
Sphider? here is a little about it.
Sphider is a web spider and search engine, suitable for adding search functionality to small or medium sites (up to 20,000 pages). It can index both static and dynamic pages, supports boolean and phrase searches and includes an option to build a searchable Yahoo-like directory system. Uses MySQL as its back end database.
