• If you are trying to use Boolean operators, they must be ALL CAPS: ((long tin) OR (long tip)) can china wen ping jia ((tong hui) OR (gong si)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long tin) OR (long tip)) can china wen ping jia ((tong hui) or (gong si)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((long tin) OR (long tip)) can china wen ping jia ((tong hui) or (gong si)) ;*.
