• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (theo chieu)) sang - canh tranh cua tong cong ((van phan) OR (luan phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (theo chieu)) sang - canh tranh cua tong cong ((van phan) OR (luan phan)) cau*.
