• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang cai hoi. hieu va cao luc ((((va hanh) OR (va tinh))) OR (dia danh)) vai cua triet.
• Adding a wildcard symbol may retrieve word variants: su sach ky nang cai hoi. hieu va cao luc ((((va hanh) or (va tinh))) or (dia danh)) vai cua triet*.
