• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (dong sign)) ya hua rent yan thi ((hong hai) OR (shang hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong sign)) ya hua rent yan thi ((hong hai) OR (shang hai)) ;".
