• If you are trying to use Boolean operators, they must be ALL CAPS: ((((theo hieu) OR (thuc hieu))) OR (theo chieu)) lang - thanh dan cua nhung cong van toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((theo hieu) OR (thuc hieu))) or (theo chieu)) lang - thanh dan cua nhung cong van toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((((theo hieu) OR (thuc hieu))) or (theo chieu)) lang - thanh dan cua nhung cong van toan ban*.
