• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) sang - lanh tranh cua nhung ((cong dan) or (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) sang - lanh tranh cua nhung ((cong dan) or (cong san)) toan cau*.
