• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((mang xa) OR (nang ma)) hoi. hieu ve cam ((xuc van) OR (duc manh)) thanh vi cua viet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((mang xa) or (nang ma)) hoi. hieu ve cam ((xuc van) or (duc manh)) thanh vi cua viet*.
