Let me add just one thought on the single term searches: I do not think that a good search result for such terms as "philosophy" should focus on the primary meaning of the term alone. As someone else had pointed out, the beauty brand can be quite important for some people. If we look at a search engine as a tool that needn't present me with near perfect results from the outset, but something I can have a dialogue with to find something, than it is best that results for single terms presents me with a variety of different special meanings (and probably some useful suggestions how to refine my search). Perhaps you can scrap the Wikipedia disambiguation pages and use it somehow to refine your search results.
