• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((((yan yuan) OR (yan guan))) OR (wang yuhan)) fei chen shuang jin jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((((yan yuan) OR (yan guan))) or (wang yuhan)) fei chen shuang jin jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((((yan yuan) OR (yan guan))) or (wang yuhan)) fei chen shuang jin jeong shu ;*.
