With the example in the screen shot above, note that the at-sign gets stripped, and the search is done for "clip" rather than "@clip", which makes it harder to find what I really want. Other symbols (for example '[') also seem to be stripped. I'm guessing that your answer will be that you have no control over that, so we'll live with it. Or maybe there is a good reason for it. (But you probably will not give my wished-for answer: Oh, that's easy to fix for the next version. :-)
