Question

我有以下的Nest查询来删除所有匹配的文档，非常简单，但我收到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);

感谢您的帮助。

请求正文

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

回应机构

{"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,

听起来您可能正在将Nlastic 2.x与Elasticsearch 2.x结合使用。作为Elasticsearch 2.0的一部分，需要安装Delete by query was moved out of Elasticsearch core and into a separate plugin。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”现在应按预期工作。

如果您需要获取有关请求失败原因的更多详细信息，可以检查响应中的.DebugInformation以获取请求的审计跟踪。
