• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong tan) OR (dong nan)) tan ((china won) OR (china wang)) ying jin ((gong hui) OR (gong si)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong tan) or (dong nan)) tan ((china won) OR (china wang)) ying jin ((gong hui) or (gong si)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong tan) or (dong nan)) tan ((china won) OR (china wang)) ying jin ((gong hui) or (gong si)) ;*.
