• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu hoach)) ky nang ((x hoi) OR (o hoi)). hieu va cac tuc va danh dien cua te~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu hoach)) ky nang ((x hoi) or (o hoi)). hieu va cac tuc va danh dien cua te*.
