elasticsearch - Elasticsearch POST/delete_by_query不起作用

Question

我试图使用POST / delete_by_query在Elasticsearch中删除文档，但是在执行时并没有删除文档，但是没有引发错误。有趣的是，它适用于某些索引，但不适用于其他索引。有什么原因会发生这种情况吗？

POST /my-index/_delete_by_query?slices=1&requests_per_second=-1&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&ignore_throttled=true&refresh=true&conflicts=proceed&wait_for_completion=true

  "query": {

      "must": [
        {
          "bool": {
            "must": [
              {
                "terms": {
                  "myAttributeKey1": [
                    "myAttributeValue1"
                  ],
                  "boost": 1
                }
              }
            ],
            "adjust_pure_negative": true,
            "boost": 1
          }
        },
        {
          "query_string": {
            "query": "myAttributeValue2",
            "fields": [
              "myAttributeKey2"
            ],

  },

}

事实证明，索引映射是个问题。以下是索引映射。我应该使用myAttributeKey1.keyword而不是myAttributeKey1这个词，可以通过修复索引映射来解决。

{
  "mapping": {
    "_doc": {
      "properties": {
        "myAttributeKey1": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        }
      }
    }
  }
}

这是您可能想要的映射的比较

{
  "mapping": {
    "_doc": {
      "properties": {
        "_class": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "myAttributeKey1": {
          "type": "keyword"
        }
      }
    }
  }
}
