• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh mang) OR (hanh trang)) cac truong ((cuong hai) OR (cong hai)) quan cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh mang) or (hanh trang)) cac truong ((cuong hai) OR (cong hai)) quan cap".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh mang) or (hanh trang)) cac truong ((cuong hai) OR (cong hai)) quan cap*.
