Former Google search experts have revealed what they hope will be a threat to their previous employer’s dominant search service. The new engine is named Cuil, after the Gaelic word for “wisdom.” It’s perhaps not the catchiest name ever, but neither was Google, before it became a household name. The people at Cuil claim the new search engine uses far fewer servers than the search leader, yet indexes a much larger chunk of the Web. It also purports to produce more relevant search results, because the information it returns in response to queries is based on organization of ideas rather than link popularity. A final—and important—differentiator from Google is that Cuil, according to the company, doesn’t collect information on its users’ search histories or IP addresses. Of course, that last advantage is significant only if the product is worth using.
