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