(2003-08-11) Nutch Search Engine

Intro to Nutch, a nascent Open Source Search Engine (intended to handle public-site performance). Hosted by the Internet Archive, and its board of advisors includes Mitch Kapor and Tim OReilly. Could be a good choice for a VerticalSearch Engine service.

Update : Doug Cutting, the creator of Lucene and V Twin, did the meat of the code.
