• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang yang)) ((wuhan china) OR (tuan china)) tan ying dan yang haji ;~.
• 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 yang haji ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yang)) ((wuhan china) OR (tuan china)) tan ying dan yang haji ;*.
