In fact the modern search engine is extremely sophisticated in what it is trying to do. Most search engines these days use LSI (Latent Semantic Indexing). This presents each web page as being a vector. Some remarkable associations between websites that have got similar vectors. http://chris.ikit.org/ksv2.pdf is very impressive. It should be pointed out that LSI scanning is CPU intensive. OK once a page has been done it has been done. One thing I would like Google to do is to use vectors when searching from within a document you are writing. It does not appear to do this. It is easy to say these thing.
