• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (chiet tach)) - hanh trang cua khong cong ((dan toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chiet tach)) - hanh trang cua khong cong ((dan toan) or (van toan)) cau".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chiet tach)) - hanh trang cua khong cong ((dan toan) or (van toan)) cau*.
