• If you are trying to use Boolean operators, they must be ALL CAPS: wing ian ((yang yu) OR (((wang yue) OR (wong yue)))) chen king john kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ian ((yang yu) or (((wang yue) OR (wong yue)))) chen king john kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: wing ian ((yang yu) or (((wang yue) OR (wong yue)))) chen king john kong sar ;*.
