Building a Vector Space Search Engine in Perl

There is a very interesting article at It is about building a search engine using perl language. The interesting part is that the article is not about the usual reverse index type search engines. It takes a different approach – vector space searching.

Reading the article reminded me of the few things:

  • The subject of searching is interesting to me.
  • Perl is great!
  • Linear algebra is actually useful and I should take it again (and pass it this time).
