I came across this interesting project by Maciej Ceglowski in creating a Semantic Search Engine. He is currently looking for content providers to help in the project. ::: www.idlewords.com/movable_type.htm He also mentions an interesting link to more non-technical information on the fuzzy-search technique called latent semantic indexing. ::: http://javelina.cet.middlebury.edu/lsa/out/lsa_intro.htm
