• If you are trying to use Boolean operators, they must be ALL CAPS: liang ((china zhang) OR (yi chang)) win your song ming ((hung a) OR (hung cam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "liang ((china zhang) or (yi chang)) win your song ming ((hung a) OR (hung cam)) ;~".
• Adding a wildcard symbol may retrieve word variants: liang ((china zhang) or (yi chang)) win your song ming ((hung a) OR (hung cam)) ;*.
