• If you are trying to use Boolean operators, they must be ALL CAPS: co sach y nang x hoi. hieu ve cam xuc van thanh vi ((((cua thep) OR (cua triet))) OR (cuu tre)).
• Adding a wildcard symbol may retrieve word variants: co sach y nang x hoi. hieu ve cam xuc van thanh vi ((((cua thep) or (cua triet))) or (cuu tre))*.
