• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach 2) OR (sach nay))) OR (sach y)) nang ma hoi. hieu vu cham cuu va dan di cua te~.
• Adding a wildcard symbol may retrieve word variants: te ((((sach 2) or (sach nay))) or (sach y)) nang ma hoi. hieu vu cham cuu va dan di cua te*.
