• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan tan china who ((((yang jin) or (wang lin))) or (((wang qin) OR (wang ning)))) zong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan tan china who ((((yang jin) or (wang lin))) or (((wang qin) OR (wang ning)))) zong hai ;*.
