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