I'm trying to search for a user group through the public API, using for instance:

$query = new Query();
                
$query->criterion = new Criterion\Field(
'name',
Criterion\Operator::EQ,
'Editors'
);

$resultParents = $searchService->findContent( $query );

If the group I want to search if any of the default user groups Editors or Administrator users, it doesn't find them, but the other default ones it does.
However, if I edit those groups it cannot find, and simply republish them, now it can find them.
