• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. lieu va ((((dam thuc) OR (nam thuoc))) OR (cam xuc)) va hanh dai va triet.
• Adding a wildcard symbol may retrieve word variants: su sach y lang xa hoi. lieu va ((((dam thuc) or (nam thuoc))) or (cam xuc)) va hanh dai va triet*.
