While some bloggers seem to think that Google is invincible, there are plenty of people racing into the web search game with new approaches. One new search engine is EigenCluster. Developed by a small group of MIT and Yale researchers, EigenCluster is a meta-search engine that groups the results of a websearch like leaves along a single branch of a tree. A search on the phrase "chemistry links" produces groupings such as college courses, science departments, and library resources. The total number of results is less than that found in a Google search, but who reads past the first few pages of search results anyway? The EigenCluster About page limits information about the search engine to two academic papers, which you can read here.
