Why does it need to be that extensive? I think that it might be more useful to keep very specific information walled off from general information. I think finding information would be too noisy otherwise. For instance, if I&#x27;m searching for ash on wikipedia I probably want wood or volcanic ash. But if I&#x27;m searching for ash on a pokemon wikipedia I want info on the main character.<p>Getting good search results is definitely a problem that a ton of people have spent time working on. But I don&#x27;t really think that it is that important of a problem in some cases. Sure, it might be nice if wikipedia could accurately distinguish whether I wanted info on wood ash or Ash the fictional character, but that creates problems. It basically makes implicit assumptions about what I am interested in. And sometimes it can be nice to have less intelligent results.
