• If you are trying to use Boolean operators, they must be ALL CAPS: wan a china ((wen chin) OR (en chine)) huang kong ((chong wan) OR (chong en)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan a china ((wen chin) or (en chine)) huang kong ((chong wan) OR (chong en)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan a china ((wen chin) or (en chine)) huang kong ((chong wan) OR (chong en)) ;*.
