• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing tan) OR (dong sin)) ming zhang ying jae song ((ping yu) OR (ping yi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing tan) or (dong sin)) ming zhang ying jae song ((ping yu) OR (ping yi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing tan) or (dong sin)) ming zhang ying jae song ((ping yu) OR (ping yi)) ;*.
