A new search engine created by former engineers from Google Inc. launched Sunday night, claiming to cover three times as many Web pages as Google.

Menlo Park-based Cuil Inc. was created by Anna Patterson, her husband, Tom Costello, Russell Power and Louis Monier and is backed by about $33 million in venture funding.

Cuil, pronounced cool, promises not to retain information about its users' search histories or surfing patterns, unlike Mountain View-based Google (NASDAQ:GOOG).

Patterson worked with Power at Google in 2004 after it bought a previous search index she developed called Recall.

Monier is the former chief technology officer of AltaVista, the search engine Google supplanted in the late 1990s. He also eBay Inc.'s (NASDAQ:EBAY) search engine for its online auction site.

Cuil, which formerly spelled its name with two L's as Cuill, most recently raised $25 million in April in a round of funding led by Menlo Park-based Madrone Capital Partners.
