• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach ky nang xa hoi. hieu ke cau luc ((((va hanh) OR (ban hanh))) OR (van hanh)) vi cua triet.
• Adding a wildcard symbol may retrieve word variants: vu khach ky nang xa hoi. hieu ke cau luc ((((va hanh) or (ban hanh))) or (van hanh)) vi cua triet*.
