• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chinh sach) OR (chieu tinh)) - hanh tranh va ((hang cong) OR (dang cong)) thanh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chinh sach) or (chieu tinh)) - hanh tranh va ((hang cong) OR (dang cong)) thanh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chinh sach) or (chieu tinh)) - hanh tranh va ((hang cong) OR (dang cong)) thanh toan cau*.
