Filter by additional fields listed in the URL browser

[NicoHaase]

We'd like to filter results based on the Fetch status listed in the URL browser, but that does not work in our context. Through

$request->negativeFilter('fetch:Gone');

I had expected that no rows with that status were returned, but that is not the case. Is there any other way to filter for this state or the HTTP status code of a document?

Background: currently, we have a lot of 404 documents in the index which should not be returned. Yes, we will also adjust the index through scheduled jobs, but adjusting it this way takes more time as we use a lot of indices
