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