• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang cao hoi. lieu va ((((cam tuc) OR (nhan thuc))) OR (cam xuc)) va hang hai va triet.
• Adding a wildcard symbol may retrieve word variants: su sach y nang cao hoi. lieu va ((((cam tuc) or (nhan thuc))) or (cam xuc)) va hang hai va triet*.
