blessing - "Wrong" Berachoth exempting foods


'Al HaMihyah exempts 'Al Ha'Gefen, at least if it was said after eating grain products and grape juice/wine. Is this unique to this case, or is there a broader principle?


Can a less specific Berachah exempt a food that is more "important", because it is broad, or is it not "powerful" enough for that "higher" food? On the flip side, can a more specific Berachah exempt a "lower" food, because it is more "powerful", or is it too specific and not applicable to other foods?
