• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang ((ma hoi) OR (ma hoa)). hieu ((ve cham) OR (ve chat)) duc va hanh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang ((ma hoi) OR (ma hoa)). hieu ((ve cham) or (ve chat)) duc va hanh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang ((ma hoi) OR (ma hoa)). hieu ((ve cham) or (ve chat)) duc va hanh lai cua tre*.
