Solarium execute custom query

Question

How can I execute query /solr/<core>/schema/fields or any direct uri in Solarium? I found some codes but I don't know how to use them:

$request = $client->createRequest($query);
$response = $client->executeRequest($request);
$result = $client->createResult($query, $response);

You can use file_get_contents('/your/endpoint') to query a solr-uri. If you need to do POST to an endpoint you Guzzle.
