• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu dang ((ha hoi) OR (hoa hoi)). hieu ve cac xuc va thanh viec ((cua cu) OR (cua cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu dang ((ha hoi) or (hoa hoi)). hieu ve cac xuc va thanh viec ((cua cu) OR (cua cau))".
