• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (wang yang)) ya hua ren shang tan ((wong shiu) OR (wong siu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (wang yang)) ya hua ren shang tan ((wong shiu) OR (wong siu)) ;".
