• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (hien hanh)) - canh tranh cua dung cong ((van phan) OR (luan phan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (hien hanh)) - canh tranh cua dung cong ((van phan) OR (luan phan)) cau*".
