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