I hear you. But arguably, imagine you could search a "collection" after you drilled down into your category.

  Top -> Finance -> Credit Card -> Merchant Fees + Search
  Top -> Finance -> Stock Market -> Algorithms + Search
  Top -> Health -> Vitamins + Search

And of course, the Wikipedia is a good jumping off point for all of that information. But imagine a wikipedia-like place that then allowed you to find the top level information that you're looking for with additional search capabilities in its supporting collection.

Maybe the start of this is taking a Wikipedia article on Price Parity and then enumerating the referenced articles in the footnotes and putting a search engine over those perhaps.

I don't know. But there's got to be something better than what we have right now. I feel another leap of search innovation happening soon.
