• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan yi ((juan rene) OR (juan meng)) ((chan ming) OR (tuan mine)) cong sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yi ((juan rene) OR (juan meng)) ((chan ming) or (tuan mine)) cong sun ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yi ((juan rene) OR (juan meng)) ((chan ming) or (tuan mine)) cong sun ;*.
