I vaguely recall that there used to be a feature (and possibly this was with Altavista before I switched to Google) that allowed you to search for words that were close together. So instead of trying ten different permutations of "like jb hifi in London" I would enter the keywords, and various forms "jb hifi type stores in London", "jb hifi stores in central London" etc would be returned. Or am I dreaming?
