• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ve cac tro ta danh vai ((((cua tre) OR (cua te))) OR (cua tu)).
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ve cac tro ta danh vai ((((cua tre) or (cua te))) or (cua tu))*.
