• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach y) OR (sach ty)) nang ((ma hoi) OR (ma hoa)). hieu le ta thu va hanh di cua viet~.
• Adding a wildcard symbol may retrieve word variants: vu ((sach y) or (sach ty)) nang ((ma hoi) or (ma hoa)). hieu le ta thu va hanh di cua viet*.
