• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang xa) OR (nang x)) hoi. hieu van cham ((xuc va) OR (duc va)) von mai va tieu.
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang xa) or (nang x)) hoi. hieu van cham ((xuc va) or (duc va)) von mai va tieu*.
