If you want to filter articles by person, the result is always empty.

I think the problem is related to the used MatchQuery at ArticleController.php#L296.

Shouldn't this be like this?

$contactIds = explode(',', $filter['contactId']);
$boolQuery = new BoolQuery();
$boolQuery->add(new TermsQuery('changer_contact_id', $contactIds), BoolQuery::SHOULD);
$boolQuery->add(new TermsQuery('creator_contact_id', $contactIds), BoolQuery::SHOULD);
$boolQuery->add(new TermsQuery('author_id', $contactIds), BoolQuery::SHOULD);
