ES-基本操作

（1）创建索引

put 192.168.247.197:9200/type2

192.168.247.197:9200/type2

（2）创建映射

post 192.168.247.197:9200/type2/type/_mapping

{
   "properties": {
        "id": {
            "type": "String"
        },
        "name": {
            "type": "String"
        },
        "desc": {
            "type": "String"
        },
        "createtime": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
        },
        "modifiytime": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
        }
    }
}

注：es 2.3.5上面还没有text这种类型，"type":"text" 改为 "type":"String"即可

在这片文章中介绍了ES2.3.5版本中ES的数据类型：https://www.cnblogs.com/excellencesy/p/11736079.html

(3)添加文档

POST 192.168.247.197:9200/type2/type

{
"id": "002",
"name": "zhangsan",
"desc": "hahahah",
"createtime": "2011-12-17",
"modifiytime": "2011-12-11"
}

（4）排序查询

{
  "query": {
    "match": {

    }
  },
  "sort": [
    {
      "createtime": {
        "order": "desc"
      }
    }
  ]
