Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no {transforms} that match.

* Contains wildcard expressions and there are only partial matches.

The default value is `true`, which returns an empty `transforms` array when
there are no matches and the subset of results when there are partial matches.

the appropriate {transforms}. For example, if the request contains
`test-id1*,test-id2*` as the identifiers and there are no {transforms}
that match `test-id2*`, the API nonetheless stops the {transforms}
that match `test-id1*`.
