• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky nang xa hoi. lieu va nam tu ((va hanh) OR (dia danh)) vi su triet.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ky nang xa hoi. lieu va nam tu ((va hanh) or (dia danh)) vi su triet*.
