Hello,

searching to filter search results by language, I had hard time to find the right "TAG" for the search exclude query. I put here my solution to filter the search results by language using search_exclude module:

In a [MY–MODULE].module file:

use Drupal\Core\Database\Query\AlterableInterface;
/**
 * Implements hook_query_TAG_alter(): tag search_$type with $type search_exclude_node_search
 * the TAG part = search_search_exclude_node_search (!!!)
 * 
 *  @return Search results in current language
 */
function [MY–MODULE]_query_search_search_exclude_node_search_alter(AlterableInterface $query) {
  $language = \Drupal::languageManager()->getCurrentLanguage()->getId();
  $query->condition('n.langcode', $language, '=');
}

Once you find the TAG, so simple :-)
