• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((((hanh trang) OR (minh trang))) OR (thanh trung)) van dung trong tan thanh cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((((hanh trang) OR (minh trang))) or (thanh trung)) van dung trong tan thanh cac*".
