Elasticsearch创建文档，利用Kibana进行创建文档

首先先来了解一下什么是文档，es里边的文档相当于mysql数据库里边的一张表，如果你用过mongodb的话，那么肯定对es这种数据格式一定很了解了。接下来我们来看一下如何创建一个文档。

PUT /sdb/user/1
{
  "username":"张三",
  "age":16,
  "gender":"男",
  "about":"this is my info",
  "addrs":["甘肃","陕西","兰州"]
}

执行成功后结果如下:

{
  "_index" : "sdb",
  "_type" : "user",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 4,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

这时我们已经给sdb索引添加了一个文档，我们来查看一下命令

GET /sdb/user/1

查看user文档ID为1

GET /sdb/user/q
{
  "_index" : "sdb",
  "_type" : "user",
  "_id" : "1",
  "_version" : 1,
  "_seq_no" : 0,
  "_primary_term" : 1,
  "found" : true,
  "_source" : {
    "username" : "张三",
    "age" : 16,
    "gender" : "男",
    "about" : "this is my info",
    "addrs" : [
      "甘肃",
      "陕西",
      "兰州"
    ]
  }
}

执行成功，说明已经检索出来了，

创建我们会了，下面我们来说说如何修改一个已经存在的文档，命令如下：

//根据ID来修改，把之前的张三修改为张三名
POST /sdb/user/1
{
  "username":"张三名",
  "age":16,
  "gender":"男",
  "about":"this is my info",
  "addrs":["甘肃","陕西","兰州"]
}

执行成功后输出入下

{
  "_index" : "sdb",
  "_type" : "user",
  "_id" : "1",
  "_version" : 4,
  "result" : "updated",
  "_shards" : {
    "total" : 4,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 3,
  "_primary_term" : 1
}

到这里创建和修改我们都会了，下面我们来看看如何删除一个文档呢，命令如下

DELETE /sdb/user/1

1代表删除文档ID为1的，以上代码执行结果如下：

{
  "_index" : "sdb",
  "_type" : "user",
  "_id" : "1",
  "_version" : 5,
  "result" : "deleted",
  "_shards" : {
    "total" : 4,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 4,
  "_primary_term" : 1
}

到此已经删除成功了，我们在用GET查看，发下结果如下：

{
  "_index" : "sdb",
  "_type" : "user",
  "_id" : "1",
  "found" : false
}

以上为es中文档的创建修改和删除，有问题可以在下面评论，想讨论技术的可以私聊我。
