Orca Search

The Orca Search is a useful self-spidering site search engine script written in PHP and using MySQL to index data. The data indexed can be quickly searched through by visitors via an intuitive interface.
Note: The Orca Search is a full-text search, rather than an index-word search; this provides a few key benefits such as: complete language independence, fast spidering and highly accurate searching. However, as a result of this design, the script will only usefully scale to sites with 1,000 ~ 2,000 pages. Decent spider crawl and search return times have been reported for indexes with up to 10,000 pages, but such results are not typical.
Here are some key features of "Orca Search":
