• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((((kang chen) OR (yan clan))) OR (man han)) rui tan ((hong tin) OR (hung tien)) hong tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((((kang chen) or (yan clan))) or (man han)) rui tan ((hong tin) OR (hung tien)) hong tan ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((((kang chen) or (yan clan))) or (man han)) rui tan ((hong tin) OR (hung tien)) hong tan ;*.
