• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly quang ((ma hoi) OR (ma hoa)). hieu ((ve cac) OR (ve cham)) luc va thanh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly quang ((ma hoi) OR (ma hoa)). hieu ((ve cac) or (ve cham)) luc va thanh dai cua te*".
