• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan klang iii gene ((yang jin) OR (yang jie)) ((song yun) OR (young yun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan klang iii gene ((yang jin) OR (yang jie)) ((song yun) or (young yun)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan klang iii gene ((yang jin) OR (yang jie)) ((song yun) or (young yun)) ;*.
