• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (so sach)) ky lang ha hoi. hieu qua cac xuc ((va danh) OR (va dan)) du cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (so sach)) ky lang ha hoi. hieu qua cac xuc ((va danh) OR (va dan)) du cua viet*".
