Elasticsearch DeleteByQuery无法正常工作,获得400个错误请求

Question

我有以下的Nest查询来删除所有匹配的文档,非常直接,但我收到了400个错误的请求.

 var client = new ElasticClient();
        var request = new DeleteByQueryRequest<Type>("my-index")
        {
            Query = new QueryContainer(
                    new TermQuery
                    {
                        Field = "versionId",
                        Value = "ea8e517b-c2e3-4dfe-8e49-edc8bda67bad"
                    }
                )
        };
        var response = client.DeleteByQuery(request);
        Assert.IsTrue(response.IsValid);

谢谢你的帮助.

请求机构

{"query":{"term":{"versionId":{"value":"ea8e517b-c2e3-4dfe-8e49-edc8bda67bad"}}}}

响应机构

{"took":0,"timed_out":false,"_indices":{"_all":{"found":0,"deleted":0,"missing":0,"failed":0}},"failures":[]}

在Sense插件中查询:

GET /my-index/type/_search
{
  "query": {

          "match": {
             "versionId": "ea8e517b-c2e3-4dfe-8e49-edc8bda67bad"
          } 

  }
}

查询响应:

{
   "took": 3,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 116,
      "max_score": 2.1220484,
      "hits": []
...
}}

--------------- NEST QUERY --------------

DELETE http://localhost:9200/my-index/component/_query?pretty=true
{

        "value": "ea8e517b-c2e3-4dfe-8e49-edc8bda67bad"
      }
    }
  }
}

Status: 200
{
  "took" : 0,
  "timed_out" : false,
  "_indices" : {
    "_all" : {
      "found" : 0,

    }
  },
  "failures" : [ ]
}

听起来你可能正在使用Elasticsearch 2.x和NEST 2.x. 作为Elasticsearch 2.0的一部分,按查询删除已从Elasticsearch核心移出,并转移到需要安装的单独插件中.您可以使用Elasticsearch bin目录中的以下命令安装插件

bin/plugin install delete-by-query

再次启动节点,按查询删除现在应该按预期工作.
