• If you are trying to use Boolean operators, they must be ALL CAPS: ((long thanh) OR (dong sin)) fang yuan ming qing song ((chong siu) OR (chong yi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long thanh) or (dong sin)) fang yuan ming qing song ((chong siu) OR (chong yi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((long thanh) or (dong sin)) fang yuan ming qing song ((chong siu) OR (chong yi)) ;*.
