I want to alter the results of a Drupal 8.x search_api_solr search using hook_search_api_solr_search_results():

function sbn_search_api_solr_search_results_alter(Drupalsearch_apiQueryResultSetInterface $result_set,                                                       Drupalsearch_apiQueryQueryInterface $query,                                                         SolariumQueryTypeSelectResultResult $result) {  $resultset_data = $result->getData();   // Get docs in response results   $results = $resultset_data['response']['docs'];   foreach ($results as $id => &$item) {     // get the doc and array id   } } 

I know that the docs I seek are in the search results:

dsm($result); 

returns

stdClass Object (     [__CLASS__] => SolariumQueryTypeSelectResultResult     [numfound:protected] => 5     [maxscore:protected] => 1.8644972     [nextcursormark:protected] =>      [documents:protected] => Array         (             [0] => stdClass Object                 (                     [__CLASS__] => SolariumQueryTypeSelectResultDocument                     [fields:protected] => Array                         (                             [ss_search_api_id] => entity:node/47:en                             [ss_search_api_language] => en                             [score] => 1.8644972                         )   ...     [data:protected] => Array         (             [response] => Array                 (                     [numFound] => 5                     [start] => 0                     [maxScore] => 1.8644972                     [docs] => Array                         (                             [0] => Array                                 (                                     [ss_search_api_id] => entity:node/47:en                                     [ss_search_api_language] => en                                     [score] => 1.8644972                                 )                              [1] => Array                                 (                                     [ss_search_api_id] => entity:file/85:en                                     [ss_search_api_language] => en                                     [score] => 1.784599                                 ) 

Let’s say that the doc in question that I want to remove from $result object is:

$resultset_data['response']['docs'][$id] 

How do I alter the $result object to remove this doc from results? Every attempt I have made to access the $result object as an array has resulted in these types of errors:

Error: Cannot use object of type SolariumQueryTypeSelectResultResult as array

Error: Cannot access protected property SolariumQueryTypeSelectResultResult::$response

Any suggestions or documentation on this would be highly appreciated.
