• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ((me hoi) OR (ma hoa)). thien ((van cay) OR (van ca)) dua ban hang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ((me hoi) or (ma hoa)). thien ((van cay) OR (van ca)) dua ban hang tai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ((me hoi) or (ma hoa)). thien ((van cay) OR (van ca)) dua ban hang tai cua tre*.
