• The words AND, OR and NOT may confuse the search; try adding quotes: "hong kong yan di erence ((zhang jing) OR (zhang ping)) ((hong ghi) or (dang hadi)) ;~".
• Adding a wildcard symbol may retrieve word variants: hong kong yan di erence ((zhang jing) OR (zhang ping)) ((hong ghi) or (dang hadi)) ;*.
