Carrot Clustering Engine

There's a new search engine which you may like to look at. The results are given in "thematic categories." This means that the results are presented under various headings, e.g. for a search using the term 'library,' the categories are public library, research library etc. It also produces a list of the sources and types of sites from each search. A facility for searching PubMed is also available. Only a small number of results appear - not necessarily a bad or permanent feature. The URL for the search is: http://demo.carrot2.org/demo-stable/main
