• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((wing ian) OR (wing tan)) w gene sang mun ((leong mi) OR (jeong mi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wing ian) or (wing tan)) w gene sang mun ((leong mi) OR (jeong mi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wing ian) or (wing tan)) w gene sang mun ((leong mi) OR (jeong mi)) ;*.
