No, not safe.
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.
