• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ning) or (((wang yang) OR (wang yan)))) tan hua brain yan ((jiu kong) or (jiu cong)) sara ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ning) or (((wang yang) OR (wang yan)))) tan hua brain yan ((jiu kong) or (jiu cong)) sara ;*.
