• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((lang xa) OR (nang ma)) hoi. hieu ve cac ((xuc va) OR (tuc xa)) danh vai cua tre.
• Adding a wildcard symbol may retrieve word variants: su sac ky ((lang xa) or (nang ma)) hoi. hieu ve cac ((xuc va) or (tuc xa)) danh vai cua tre*.
