• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) sach - ((nhanh lang) OR (nhan dang)) van hung cong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) sach - ((nhanh lang) OR (nhan dang)) van hung cong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) sach - ((nhanh lang) OR (nhan dang)) van hung cong manh toan cao*.
