class_docstr: The ElasticSearchResponse class is used to manage and access the response from an Elasticsearch search.
  
  This class can be iterated over directly to access hits in the response. Indexing the class instance
  with an integer or slice will also access the hits. The class also evaluates to True
  if there are any hits in the response.
  
  The hits property returns an AttributeList of hits in the response, with each hit transformed into
  an instance of the doc_class if provided.
  
  The response parameter stores the dictionary returned by the Elasticsearch client search method.
