json - 弹性query_string返回不需要的值

我正在尝试根据群集字段以及podName字段是否具有值进行过滤。
然后，我想过滤掉某些具有特定值的字段，但获得除指定的群集字段以外的其他值。
因此，以下查询还将返回cluster2和cluster3的值。
我不知道什么是正确的语法。

{
   "size":50,
   "query":{
      "bool":{
         "must":[
            {
               "range":{
                  "timestamp":{
                     "gte":"now-1h"
                  }
               }
            },
            {
               "query_string":{
                  "query":"(podstatus.podName:* AND cluster:cluster1) AND NOT podstatus.containerStatus:true AND NOT podstatus.phase:Running AND NOT podstatus.phase:Succeeded AND NOT podstatus.started: true"
               }
            }
         ]
      }
   }
}

您的查询似乎工作正常。但是，我将发布以下步骤，如果您能以类似方式找到任何观察结果，请告诉我。
我已经完成了映射，创建了示例文档，您共享的查询以及得到的响应。

您也可以像上面的 cluster.keyword一样使用上面的 cluster.keyword:cluster1进行精确匹配。

请注意查询正常工作并返回正确的文档集
其他调试和更多信息:
此步骤将帮助您进行验证，并让您知道为什么不应该返回的文档正在返回。
例如，对于我来说，样本中的第3个文档没有出现在响应中，而找出该问题的方法是利用 Explain API. 
GET cluster_index_001/_explain/3       <----- Note this
{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "timestamp": {
              "gte": "now-2d"
            }
          }
        },
        {
          "query_string": {
              "query":"podstatus.podName:* AND cluster:cluster1 AND NOT podstatus.containerStatus:true AND NOT podstatus.phase:Running AND NOT podstatus.started: true"
          }
        }
      ]
    }

                "description" : "no match on required clause (cluster:cluster1)",
                "details" : [
                  {
                    "value" : 0.0,
                    "description" : "no matching term",
                    "details" : [ ]
                  }
                ]
              }
            ]
          }
        ]
      }
    ]
  }
}
请注意，以上响应中的描述如何清楚地说明这一点: 
"description" : "Failure to meet condition(s) of required/prohibited clause(s)"
另请注意以下几点: 
"description" : "no match on required clause (+ConstantScore(NormsFieldExistsQuery [field=podstatus.podName]) +cluster:cluster1 -podstatus.containerStatus:true -podstatus.phase:running -podstatus.started:true)",
结果，您现在知道了为什么文档3没有返回响应。
此外，如果仍然无法解决问题，请确保以下几点:
  • 确保您没有使用任何别名，并且一次只关注单个索引。如果使用别名，请缩小可能导致此问题的索引。
  • 还请确保您所讨论的文档中没有多个值，例如"cluster": "cluster2, cluster1"
  • 如果以上两点都清楚，请转到浏览器并键入http://<your_host_name>:<port>/cluster-resources-cluster1-2020.07.08-000001/_settings，然后观察是否有针对以下目的实现的自定义分析器: Edge Ngrams或Ngrams，以及您的standard分析器是否已被覆盖。
  • 执行此http://<your_host_name>:<port>/cluster-resources-cluster1-2020.07.08-000001/_stats?pretty，并注意是否发现任何奇怪的东西。

    • 一次做一件事，请分享您的看法，我们可以看到问题所在。
