• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu bang ((x hoi) OR (o hoi)). hieu ((ve cam) OR (ve cham)) xuc van hang di cua viet~.
• Adding a wildcard symbol may retrieve word variants: su sach thu bang ((x hoi) or (o hoi)). hieu ((ve cam) or (ve cham)) xuc van hang di cua viet*.
