-* Contains wildcard expressions and there are no {datafeeds} that match.
-* Contains the `_all` string or no identifiers and there are no matches.
-* Contains wildcard expressions and there are only partial matches.

-If this parameter is `false`, the request returns a `404` status code when there

+(string) The status of the {dfeed}, which can be one of the following values:
