如果针对于某个字段,那么它的结构如下:
{
  QUERY_NAME:{   # 使用的功能
     FIELD_NAME:{  #  功能参数
       ARGUMENT:VALUE,
       ARGUMENT:VALUE,...
      }   
   }
}
示例  使用时不要加#注释内容
GET bank/_search
{
  "query": {  #  查询的字段
    "match_all": {}
  },
  "from": 0,  # 从第几条文档开始查
  "size": 5,
  "_source":["balance"],
  "sort": [
    {
      "account_number": {  # 返回结果按哪个列排序
        "order": "desc"  # 降序
      }
    }
  ]
}
_source为要返回的字段

GET bank/_search
{
  "query": {
    "match_all": {}
  },
  "from": 0,
  "size": 5,
  "sort": [
    {
      "account_number": {
        "order": "desc"
      }
    }
  ],
  "_source": ["balance","firstname"]
}
{
  "took" : 18,  #   花了18ms
  "timed_out" : false,  # 没有超时
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1000,  # 命令1000条
      "relation" : "eq"   
    },
    "max_score" : null,
    "hits" : [
      {
        "_index" : "bank",
        "_type" : "account",
        "_id" : "999",  # 第一条数据id是999
        "_score" : null,  # 得分信息
        "_source" : {
          "firstname" : "Dorothy",
          "balance" : 6087
        },
        "sort" : [  #  排序字段的值
          999
        ]
      },
      省略。。。
