• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((hanh trung) OR (manh trung)) tuan nhung ((cong dan) OR (cong tan)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((hanh trung) or (manh trung)) tuan nhung ((cong dan) OR (cong tan)) toan cau*".
