• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yuan fang ((((zheng song) OR (hong song))) OR (chen yong)) min song (shin OR thin) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yuan fang ((((zheng song) OR (hong song))) or (chen yong)) min song (shin or thin) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yuan fang ((((zheng song) OR (hong song))) or (chen yong)) min song (shin or thin) ;*.
