There is a Views row plugin called "Search Results" (core/modules/search/src/Plugin/views/row/SearchRow.php). This was apparently imported from a non-working row plugin in the Drupal 7 contrib Views module. However, as far as we can tell:
a) It didn't work in Drupal 7. Here's the code from there:
function search_views_plugins() {
return;
// DISABLED. This currently doesn't work.
return array(
'module' => 'views', // This just tells our themes are elsewhere.
'row' => array(
'search' => array(
'title' => t('Search'),
'help' => t('Display the results with standard search view.'),
...
b) Although it was imported into Drupal 8 initially as core/modules/views/lib/Views/search/Plugin/views/row/View.php (I think) early in the port to Views, it was never made to work and never had any tests.
c) It still has no tests and doesn't work. However, it appears in the UI when you are creating a view of nodes, as a row option. It causes the view to display nothing. See "Original issue -- Steps to reproduce" section below for steps to reproduce.
d) We do not need this plugin. If you want to make a view of search results, you can use the node Teaser view or the Fields row plugin.
e) We don't actually know what it was supposed to display.
Remove this non-working, confusing plugin, along with its config schema.
Make a patch and commit it.
The non-working plugin for search results rows in Views will no longer appear in the UI.
The non-working plugin code will no longer be in Core.
The schema for the non-working plugin will no longer be in Core.
Display of search results (or something) that include the term, in the case of my test there should be one search result.
Export of configuration is attached.
Needs work

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Confirming that in 10.1 the plugin still doesn't do anything and after the patch any page with the view is broken.
I've started on the update hook but interested in hearing thoughts. I was having a hard time finding a way to set the display to it's default value. I wonder if we should just set the display options to [] whenever the displays row plugin is this one?
