But Google search results ARE not satisfactory. The existence of Q&A forums in the age when information is broadly online (and thus is accessible to Google) indicates a need that is not answered by Google. Google's algorithm may be the best out there, but it still falls short of what is needed. Anecdotally, I often find it fails to conduct word-sense disambiguation, handle negation or answer edge case. My general impression is that Google's algorithm focuses on topical similarity (pages that talk about the query's topic) rather than answering the query.
