• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((hanh trinh) OR (canh tranh)) cua dang ((cong dan) OR (cong tan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((hanh trinh) or (canh tranh)) cua dang ((cong dan) OR (cong tan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((hanh trinh) or (canh tranh)) cua dang ((cong dan) OR (cong tan)) than cap*.
