Honestly, I don't think google-like search engines are the way to go anymore. They're being gamed. That's fine for things like Stack Overflow or finding the background of a person. But it's not good for finding a place to eat, a book to read, health advice, a specific game genre, or the best tom yum recipe. Google subsidiearies like YouTube and Google Play do a really poor job at this, and Google isn't much better.

I think what might work better is an unweighted filter. A google style search engine filters out all tom yum recipes below a certain quality or all health sites below a certain credibility level. And then it tosses you a random one. Google tries to make a one size fits all engine, so it's doing very poorly in many of these. But Bing/DDG isn't faring much better. Stack Overflow and wikis are basically just search engine plugins
