The most effective interpretation of (a AND b) I have seen is to use quorum ranking -- first list things containing both, then list things containing either, and for (a AND b AND c) sort results by the number of terms matched. And this is what some of the Web search engines do, too. There's no good answer, though, I think. You have to do user testing.
