• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing tan) OR (dong di)) gan yuan liu ((yu kang) OR (yu gang)) wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing tan) or (dong di)) gan yuan liu ((yu kang) OR (yu gang)) wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing tan) or (dong di)) gan yuan liu ((yu kang) OR (yu gang)) wong shiu ;*.
