• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang ma hoi. ((((hieu van) OR (thien van))) OR (thi van)) cam luc van hanh va cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty sang ma hoi. ((((hieu van) or (thien van))) or (thi van)) cam luc van hanh va cua tre*.
