Vector Space Search Engines in Perl

cascadefx writes "There is a great article on writing a Vector Space Search Engine in Perl over at the Orielly Network's Perl.com site. Most search engines, such as Google, use a reverse keyword index algorithm. The article, complete with code, proves yet again that there is (definitely) more than one way to do it. Try your hand. Add improvements and you may have a handy search engine for your site or... the next Google-killer."
