• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yanling ((tuan china) OR (wuhan china)) tan yang kia ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) yanling ((tuan china) or (wuhan china)) tan yang kia ((hong hai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) yanling ((tuan china) or (wuhan china)) tan yang kia ((hong hai) or (shang hai)) ;*.
