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