• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - anh tang cua nhung ((((cong dan) OR (cong san))) OR (nong san)) than man*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - anh tang cua nhung ((((cong dan) OR (cong san))) or (nong san)) than man*".
