• If you are trying to use Boolean operators, they must be ALL CAPS: wang ying yang cpm best ((hong hong) OR (hong ng)) ((jong suk) OR (yong suk)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying yang cpm best ((hong hong) or (hong ng)) ((jong suk) OR (yong suk)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying yang cpm best ((hong hong) or (hong ng)) ((jong suk) OR (yong suk)) ;*.
