• The words AND, OR and NOT may confuse the search; try adding quotes: "(zhen or chen) zhang han run gain ((ying john) OR (ying jin)) ((song sar) or (using sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: (zhen or chen) zhang han run gain ((ying john) OR (ying jin)) ((song sar) or (using sar)) ;*.
