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