• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky ((nang xa) OR (nang ma)) hoi. hieu ve cham ((xac va) OR (duc va)) thanh hai ve triet.
• Adding a wildcard symbol may retrieve word variants: te sai ky ((nang xa) or (nang ma)) hoi. hieu ve cham ((xac va) or (duc va)) thanh hai ve triet*.
