It will never work, because the computer will never be able to infer what I want. I might be looking for the movie, then five minutes later be looking for information about layer masks in Gimp. You're suggesting I should be able to type "mask" in both cases and, somehow, Google should figure out what I'm really looking for. I don't want them to even try. I can type one or two additional keywords:

    mask movie
    mask gimp

See? It's easy, and it already works.
