- user24 15y agoYeah semantic search, if solved, would address this problem. That's really what I was getting at. Stripped right down, Google is still just viewing documents as a bag of words[1]. I mean, they have pagerank and they will apply more weight to words in headings, and they have 6-gram indexes and synonyms and all that clever stuff, but at it's core it's still lexically centered not semantically centered.

- Drbble 15y agoMeaning Google makes no effort to score your whole page against each word in the dictionary, it only attempts to score 1- to 6-game from the page and inbound links? That's unfortunate.
- user24 15y agoNo. It means that for your comment, google will store each word, each pair of words, each triplet of words and so on up to 6 word long subsets. So if someone searched for 'Google makes no effort' then your comment will come up higher than a document which includes those words in a different order. http://en.wikipedia.org/wiki/N-gram http://en.wikipedia.org/wiki/N-gram
