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