• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kang) OR (yan wang)) yan hua ren shang jin ((hong shu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (yan wang)) yan hua ren shang jin ((hong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (yan wang)) yan hua ren shang jin ((hong shu) OR (wong shiu)) ;*.
