• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach v) OR (sach vay))) OR (sach y)) nang cao hoi. hieu va chat lua va don vi cua te~.
• Adding a wildcard symbol may retrieve word variants: te ((((sach v) or (sach vay))) or (sach y)) nang cao hoi. hieu va chat lua va don vi cua te*.
