Remove should_filter_query in ‘found_posts’ function in backend search

I now fixed this with the following filter:

/**
 * @param $should_filter
 * @param WP_Query $query
 *
 * @return mixed
 */
function labelvier_algolia_should_filter_query($should_filter, $query) {
	// force filtering (bug in algolia plugin?)
	global $wp_current_filter;
	$current_filter = $wp_current_filter[count($wp_current_filter) - 2];
	if($current_filter == 'found_posts') {
		$should_filter = true;
	}

	return $should_filter;
}
add_filter('algolia_should_filter_query', 'labelvier_algolia_should_filter_query', 10, 2);
