5.1  索引初始化操作；

创建索引之前可以对索引做初始化操作,

比如指定shards数量以及replicas的数量

http://192.168.32.81:9200/library/
                         PUT
{"settings":{"number_of_shards":3,"number_of_replicas":0}}

GET  方法:
http://192.168.32.81:9200/library/
                          GET
查询

{

    "library": {
        "aliases": { },
        "mappings": { },
        "settings": {
            "index": {
                "creation_date": "1473139251510",
                "number_of_shards": "3",
                "number_of_replicas": "0",
                "uuid": "EWWTPObRSpKyQW8pVgWYGQ",
                "version": {
                    "created": "2030499"
                }
            }
        },
        "warmers": { }
    }

}

获取内容；
http://192.168.32.81:9200/library/_settings/
                                    GET

{

    "library": {
        "settings": {
            "index": {
                "creation_date": "1473139251510",
                "number_of_shards": "3",
                "number_of_replicas": "0",
                "uuid": "EWWTPObRSpKyQW8pVgWYGQ",
                "version": {
                    "created": "2030499"
                }
            }
        }
    }

}

5.2 通过API创建,删除索引

        索引名称
        |
        |     |Type名称
        |     |
PUT /library/books/1 --文档ID

http://192.168.32.81:9200/library/books/1/
                              PUT
{
 "title":"Elasticsearch:The scan",
   "name" : {
           "first":"aaa",
            "last" :"bbb"
       },
       "publish_date":"2016-09-06",
        "price":"49"
}

通过_source获取指定字段名称:

http://192.168.32.81:9200/
library/books/1/?_source=price  GET

返回:
{

    "_index": "library",
    "_type": "books",
    "_id": "1",
    "_version": 10,
    "found": true,
    "_source": {
        "price": "49"
    }

}

http://192.168.32.81:9200/
library/books/1/_update                    POST

{
   "doc":{
    "price":10.001
