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