• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yang)) wuhan china tan ying dan ((yang haji) OR (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yang)) wuhan china tan ying dan ((yang haji) OR (dang hai)) ;*.
