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