• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang ((tao hoa) OR (tao hoi)). thien van ca ((dua ban) OR (qua ban)) thanh van cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang ((tao hoa) or (tao hoi)). thien van ca ((dua ban) OR (qua ban)) thanh van cuu tre".
