• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) or (hien hanh)) - canh tranh cua truong phuong ((van toan) OR (van tuan)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (hien hanh)) - canh tranh cua truong phuong ((van toan) OR (van tuan)) tap*.
