The company said it has indexed 120 billion Web pages, three times more than any other search engine, including Google.
Cuil is led by husband-and-wife team Tom Costello and Anna Patterson. Costello researched and developed search engines at Stanford University and IBM Corp., and Patterson was the architect of the Google’s large search index and led a Web page ranking team there.
The founders said the search results generated by Cuil are based on content rather than popularity and are organized by ideas. Displayed results, unlike those of the major search engines, are in magazine-style layout and include tabs along the top of the page to refine them further.
Cuil (pronounced cool) derives its name from an old Irish word for knowledge, reflecting the background of CEO Costello, who hails from Drogheda, Ireland.
