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