• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang doc loi. hieu ((ve cam) OR (ve cham)) duc va ((thanh hoa) OR (thanh phan)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang doc loi. hieu ((ve cam) OR (ve cham)) duc va ((thanh hoa) or (thanh phan)) cua tre*".
