Yioop! is a open source PHP search engine software developed by SeekQuarry. This search engine software can be used as a general purpose search engine (like Google, Bing) or custom search engine for your website (like Google Custom Search).

This search engine can be installed in any computer which has Apache webserver with PHP installed. You can even install in your home computer. You can install Yioop! in a single system or install on multiple system as distributed services for web crawling and indexing. But search results are not good as commercial search engines.

Yioop! crawls and index fast with multiple distributed crawlers and can index directories directly like Open Directory Project RDF data, Wikipedia xml dumps which uses Internet Archives (arc) format.

Yioop! released under GPLv3 open source license and still at an alpha development stage.
