My original report was based entirely on the public catalog (hence the opac tag).
Based on Jason Stephenson comments I have now tried this in the staff catalog as well (again on 3-7-3 using the CWMARS production server) and am getting what appears to be an unrelated problem: the interface hangs and doesn't return search results, "No Matching Items Were Found", or an error message. The problem in the staff client seems to be related to parentheses; the problem I reported is not. The parentheses problem in the staff client is a definitely a bug, but it is not the bug I reported.
