• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu le nam thu ha anh sai ((cua triet) OR (((cua te) OR (cua tu)))).
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ma hoi. hieu le nam thu ha anh sai ((cua triet) or (((cua te) or (cua tu))))*.
