• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yuan) OR (nan yan)) ((xi cheng) or (yi chen)) zhang xin song (shin or thin) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yuan) OR (nan yan)) ((xi cheng) or (yi chen)) zhang xin song (shin or thin) ;*.
