• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((tan tan) or (yan guan)) hua jia zhang ((li song) OR (kim song)) jin ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((tan tan) or (yan guan)) hua jia zhang ((li song) OR (kim song)) jin ;*.
