It was a long-standing issue with Drupal where users thought they could control the search result display using the 'Search result' view mode, however that view mode served a different purpose (populating the text that ended up in the snippet highlighting the search term(s)) and was recently renamed to reflect said purpose.
That brought up the suggestion though that users should be able to control the search results per content type using view modes. Here is a request for this feature in Drupal 8; I would also like to suggest it for Backdrop.
