DaveNet: Nutch, an open source search engine
Tim O’Reilly: «Actually, Nutch has no ambitions to dethrone Google. It’s just trying to provide an open source reference implementation of search to help keep Google and other search engines honest, by letting people compare the results of an engine whose algorithms and methodologies are transparent and accessible. It also aims to give a platform for people outside of the search heavyweights to research new search algorithms.»
