• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky lang van hoi. hieu ((((qua cau) OR (qua cac))) OR (quan cau)) luc van anh vu va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky lang van hoi. hieu ((((qua cau) OR (qua cac))) or (quan cau)) luc van anh vu va triet*".
