Code

protected function postQuery(ResultSetInterface $results, QueryInterface $query, $response) {
  parent::postQuery($results, $query, $response);

  // Do not alter the results if the index does not use the solr_document
  // datasource.
  $datasources = $query
    ->getIndex()
    ->getDatasources();
  if (!isset($datasources['solr_document'])) {
    return;
  }

  /** @var \Drupal\search_api_solr\SolrDocumentFactoryInterface $solr_document_factory */

  /** @var \Drupal\search_api\Item\Item $item */
  foreach ($results
    ->getResultItems() as $item) {

    // Create the typed data object for the Item immediately after the query
    // has been run. Doing this now can prevent the Search API from having to
    // query for individual documents later.
    $item
      ->setOriginalObject($solr_document_factory
      ->create($item));

    // Prepend each item's itemId with the datasource ID. A lot of the Search
    // API assumes that the item IDs are formatted as
    // 'datasouce_id/entity_id'. Of course, the ID numbers of external Solr
    // documents will not have this pattern and the datasource must be added.
    // Reflect into the class to set the itemId.
    $reflection = new \ReflectionClass($item);
    $id_property = $reflection
      ->getProperty('itemId');
    $id_property
      ->setAccessible(TRUE);
    $id_property
      ->setValue($item, 'solr_document/' . $item
      ->getId());
  }
