• The words AND, OR and NOT may confuse the search; try adding quotes: "gang sheng ((han je) or (ying jin)) chin chang wang ((kyoung yun) OR (hyoung gun)) ;~".
• Adding a wildcard symbol may retrieve word variants: gang sheng ((han je) or (ying jin)) chin chang wang ((kyoung yun) OR (hyoung gun)) ;*.
