I'm not trying to compete with Google/Bing where their work with keywords/phrases, page rank popularity, and, say, date, work well. And for a huge pile of Internet content, search, and results, they do work well. For the searches you mention, I believe that maybe for one of them it could be possible to improve on Google/Bing, but I don't believe that real AI would be needed. For describing how to build such a search engine, that might take more than the 10,000 character limit on HN posts!
