• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tri nang x hoi. lieu va cam xuc ((((va thanh) OR (gia thanh))) OR (van hanh)) vi va triet.
• Adding a wildcard symbol may retrieve word variants: su sach tri nang x hoi. lieu va cam xuc ((((va thanh) or (gia thanh))) or (van hanh)) vi va triet*.
