Who we are
Clusty got its start in Pittsburgh, PA in 2004 when the search software company Vivísimo decided to take its award-winning search technology to the web.
Vivísimo was founded in 2000 by three Carnegie Mellon University scientists who decided to tackle the problem of information overload in web search. Rather than focusing just on search engine result ranking, we realized that grouping results into topics, or "clustering," made for better search and discovery. As search became a necessity for web users, Vivísimo developed a service robust enough to handle the variety of information the everyday web user was after. The result was Clusty: an innovative way to get more out of every search.
What makes Clusty unique?
Clusty is a whole new way to search the web.
Clusty queries several top search engines, combines the results, and generates an ordered list based on comparative ranking. This "metasearch" approach helps raise the best results to the top and push search engine spam to the bottom.
But what really makes Clusty unique is what happens after you search. Instead of delivering millions of search results in one long list, our search engine groups similar results together into clusters. Clusters help you see your search results by topic so you can zero in on exactly what you're looking for or discover unexpected relationships between items. When was the last time you went to the third or fourth page of the search results? Rather than scrolling through page after page, the clusters help you find results you may have missed or that were buried deep in the ranked list.
And with a name like Clusty, it's gotta be good!

Ixquick.com is possibly another one to use instead. Looks like mostly a US-Dutch run company. The founder looks like a "Chosen" one so take your chances..
