The new search engine is named Cuil – meaning Knowledge in Irish. The founder & CEO Tom Costello names the search engine after the Gaelic word Cuil (pronounced "cool") meaning both knowledge and hazel.
Cuil’s approach to developing a search engine from scratch is different from the currently popular ones – analyzing pages to a great depth and organizing results in a rich and helpful way that allows readers to explore fully the subject of a search.
Cuil already has over 120 billion pages indexed. They run their site off two data centers, with a thousand 8-CPU servers apparently handling the index, and another 280 delivering results.
