• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (((thuoc sach) OR (hoc sach)))) y lang xa hoi. hieu ve cam tu van hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (((thuoc sach) OR (hoc sach)))) y lang xa hoi. hieu ve cam tu van hanh vai cua tre*".
