• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((co hoi) OR (co loi)). hieu vu cham xuc ((va dinh) OR (va dan)) dau cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((co hoi) OR (co loi)). hieu vu cham xuc ((va dinh) or (va dan)) dau cua te".
