Clusty is a metasearch engine eveloped by Vivísimo which offers clusters of results. Vivísimo is a company built on Web search technology developed by Carnegie Mellon University researchers. Interestingly Lycos, a search engine that was popular a decade earlier, was also developed at the same university. Clusty adds new features and a new interface to the previous Vivisimo clustering web metasearch. Different tabs also offer metasearches for news, jobs (in partnership with Indeed.com), U.S. government info and blogs. Customized tabs allow users to select sources for their own metasearch to create personalized tabs.
