• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((tang yun) OR (wang yuhan)) zhu chen zhang ((gap along) OR (gap among)) su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((tang yun) or (wang yuhan)) zhu chen zhang ((gap along) OR (gap among)) su ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((tang yun) or (wang yuhan)) zhu chen zhang ((gap along) OR (gap among)) su ;*.
