                              GET

{

    "_index": "library",
    "_type": "books",
    "_id": "8",
    "_version": 1,
    "found": true,
    "_source": {
        "titile": "Elasticsearch: The Defintive Guide",
        "name": {
            "first": "Zachary",
            "last": "Tong"
        },
        "publish_date": "2016-07-29",
        "price": "90.01"
