文档的操作

一、添加文档

DSL 语法如下：

POST /索引库名/_doc/文档id
{
  "字段1":"值1",
  "字段2":"值2",
  "字段3": {
    "子属性1": "值3",
    "子属性2": "值4"
  }
}

Kibana 测试：

POST /test/_doc/1
{
  "info":"我是一名GO和PHP程序猿",
  "email":"test123@qq.com",
  "name": {
    "firstName": "三",
    "lastName": "张"
  }
}

响应:

{
  "_index": "test",
  "_id": "1",
  "_version": 1,
  "result": "created",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 0,
  "_primary_term": 1
}

二、查询文档

DSL 语法如下：

GET /索引库名/_doc/文档id

Kibana 测试：

GET /test/_doc/1

响应:

{
  "_index": "test",
  "_id": "1",
  "_version": 1,
  "_seq_no": 0,
  "_primary_term": 1,
  "found": true,
  "_source": {
    "info": "我是一名GO和PHP程序猿",
    "email": "test123@qq.com",
    "name": {
      "firstName": "三",
      "lastName": "张"
    }
  }
}

三、删除文档

DSL 语法如下：

DELETE /索引库名/_doc/文档id

Kibana 测试：

DELETE /test/_doc/1

响应:

{
  "_index": "test",
  "_id": "1",
  "_version": 2,
  "result": "deleted",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 1,
  "_primary_term": 1
}

四、修改文档

方式1：全量修改，会删除旧文档，添加新文档；文档ID不存在时，则会自动新增文档；
DSL 语法如下：

PUT /索引库名/_doc/文档id
{
"字段1": "值1",
"字段2": "值2"
}

Kibana 测试：

PUT /test/_doc/1
{
  "info":"我是GO和PHP程序猿",
  "email":"test888@qq.com",
  "name": {
    "firstName": "四",
    "lastName": "张"
  }
}

响应:

{
  "_index": "test",
  "_id": "1",
  "_version": 2,
  "result": "updated",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 3,
  "_primary_term": 1
}

方式2：增量修改，修改指定字段值；
DSL 语法如下：

POST /索引库名/_update/文档id
{
"doc": {
"字段名": "字段值"
}
}

Kibana 测试：

POST /test/_update/1
{
"doc": {
"email": "test999@qq.com"
}
}

响应:

{
  "_index": "test",
  "_id": "1",
  "_version": 3,
  "result": "updated",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 4,
  "_primary_term": 1
}
