• If you are trying to use Boolean operators, they must be ALL CAPS: wing yanling ((hans dr) OR (hans r)) ((dan yang) OR (tan yang)) di congo a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yanling ((hans dr) OR (hans r)) ((dan yang) or (tan yang)) di congo a ;~".
• Adding a wildcard symbol may retrieve word variants: wing yanling ((hans dr) OR (hans r)) ((dan yang) or (tan yang)) di congo a ;*.
