• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang jui shen ((chang min) OR (chang won)) ((hong ghi) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang jui shen ((chang min) OR (chang won)) ((hong ghi) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang jui shen ((chang min) OR (chang won)) ((hong ghi) or (hong yu)) ;*.
