• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu va cam ((xuc van) OR (xuc ban)) ((hanh ve) OR (anh va)) cua tre.
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu va cam ((xuc van) or (xuc ban)) ((hanh ve) or (anh va)) cua tre*.
