El comando findAndModify modifica atómicamente y devuelve un único documento.
|
|
Por omisión, el documento devuelto no incluye las modificaciones realizadas en
|
|
la actualización. Para devolver el documento con las modificaciones hechas en la
|
|
actualización, use la opción <varname>new</varname>.
