• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung cap nhung ((cong tan) OR (((truong thanh) OR (truong thpt)))) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung cap nhung ((cong tan) or (((truong thanh) OR (truong thpt)))) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung cap nhung ((cong tan) or (((truong thanh) OR (truong thpt)))) toan tap*.
