/**
 * In EXT:meilisearch 9 we have switched from the SolrPhpClient to the solarium api.
 *
 * In many places of the code the class Apache_Solr_Response and the property Apache_Solr_Response::reponse is used.
 * To be able to refactor this we need to have a replacement for Apache_Solr_Response that behaves like the original class,
 * to keep the old code working. This allows us to drop the old code of SolrPhpClient and refactore the other parts step by step.
