• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. ((hieu ve) OR (hieu van)) cac luc van hanh di ((cua tu) OR (cua tuc))~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. ((hieu ve) or (hieu van)) cac luc van hanh di ((cua tu) or (cua tuc))*.
