• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cac nganh ky ((thuat hoa) OR (thuyet hoa)) hoc ) OR ( so sach ngan co huyet hoa hoc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cac nganh ky ((thuat hoa) OR (thuyet hoa)) hoc ) or ( so sach ngan co huyet hoa hoc ))".
