• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((((nhanh mang) OR (hanh mang))) OR (hanh trang)) cua thuong cong van thanh cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((((nhanh mang) OR (hanh mang))) or (hanh trang)) cua thuong cong van thanh cao~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((((nhanh mang) OR (hanh mang))) or (hanh trang)) cua thuong cong van thanh cao*.
