[MODEL] Added, that "raw" response from Elasticsearch is wrapped in Hashie::Mash for easier access

    response = Article.search query: { match: { title: { query: 'test' } } },
                              aggregations: { dates: { date_histogram: { field: 'created_at', interval: 'hour' } } }

    assert_equal 2, response.response.aggregations.dates.buckets.first.doc_count
    # => 2
