• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan zhang) OR (han chang)) ping ((tan ying) OR (fan ying)) juan meng (star OR stay) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan zhang) or (han chang)) ping ((tan ying) or (fan ying)) juan meng (star OR stay) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan zhang) or (han chang)) ping ((tan ying) or (fan ying)) juan meng (star OR stay) ;*.
