• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((manh tuong) OR (manh cuong)) cua cong chung dan ((thanh ban) OR (thanh bac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((manh tuong) OR (manh cuong)) cua cong chung dan ((thanh ban) or (thanh bac))*".
