请求通过 Elasticsearch 中的 id 失败删除记录？

Question

我正在研究Elasticsearch 5，我还没有找到删除插入其中的数据的方法。

当我查询列出记录时，elasticsearch returns this:

curl -X POST \
  http://localhost:9201/usersystem/_search \
  -d '{
    "query": {
        "terms": { "_id": [951] }
    }
}'

Return:

{
   "took":1,
   "timed_out":false,
   "_shards":{
      "total":5,
      "successful":5,
      "skipped":0,
      "failed":0
   },
   "hits":{
      "total":1,
      "max_score":1.0,
      "hits":[
         {
            "_index":"usersystem",
            "_type":"usersystem",
            "_id":"951",
            "_score":1.0,
            "_source":{
               "id":951,
               "name":"User Name",
               "email":"user.name@host.com",
               "phone":"47-1234-9876",
               "documentCode":"9876543-8",
               "documentType":"RR",
               "gender":"MALE",
               "createdOn":"2019-07-04T20:11:47.314Z",
               "updateOn":null,
               "active":false,
               "userId":952
            }
         }
      ]
   }

}

阅读一些示例，我提出了以下 DELETE 请求 returns 错误：

要求：

curl -X DELETE \
  http://localhost:9201/usersystem/_query \
  -d '{
    "query": {
        "terms": { "_id": [951] }
    }
}'

错误：No handler found for uri [/usersystem/_query] and method [DELETE]

如何通过_id或id发起删除记录的删除请求？

Answer 1

让它变成这样。

curl -X DELETE http://localhost:9201/usersystem/_doc/951

Answer 2

如果您的搜索查询 returns 以下响应，

[
  {
    "_index": "usersystem",
    "_type": "usersystem",
    "_id": "951",
    "_score": 1,
    "_source": {
      ....
  }
]

然后根据您的搜索查询的命中响应，我们了解到您的 index 名称为 usersystem type 用户系统。所以要通过 id 删除任何文档，你可以这样做-

DELETE /usersystem/usersystem/951

或

curl -X DELETE "localhost:9201/usersystem/usersystem/951"

Answer 3

我在 ElasticSearch 文档中找到了关于 _delete_by_query 的内容。这是对我有用的请购单：

curl -X POST \
  http://localhost:9201/usersystem/_delete_by_query \
  -d '{
    "query": {
        "terms": { "_id": [951] }
    }
}'
