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