• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan ban) OR (tan bann)) zhang han chang ((hong ng) OR (kong heng)) yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan ban) OR (tan bann)) zhang han chang ((hong ng) or (kong heng)) yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan ban) OR (tan bann)) zhang han chang ((hong ng) or (kong heng)) yu ;*.
