• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang or lang) yan) or (yang di)) zhang ping jia qin gai ((flying cars) OR (selling cars)) ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang or lang) yan) or (yang di)) zhang ping jia qin gai ((flying cars) OR (selling cars)) ;*.
