Elasticsearch 2.4，存在用于嵌套对象不工作的过滤器 [英] Elasticsearch 2.4, Exists filter for nested objects not working

问题描述

我的映射是：

"properties": {
  "user": {
    "type": "nested",
    "properties": {
      "id": {
        "type": "integer"
      },
      "is_active": {
        "type": "boolean",
        "null_value": false
      },
      "username": {
        "type": "string"
      }
    }
  },

我想获取所有文档没有用户字段。

I want to get all documents that do not have a user field.

我试过：

GET /index/type/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "exists": {
            "field": "user"
          }
        }
      ]
    }
  }
}

哪些返回所有文档。
根据 ElasticSearch 2 .x存在过滤器用于嵌套字段不工作，我也尝试过：

Which returns all documents. Based on ElasticSearch 2.x exists filter for nested field doesn't work, I also tried:

GET /index/type/_search
{
  "query": {
    "nested": {
      "path": "user",
      "query": {
        "bool": {
          "must_not": [
            {
              "exists": {
                "field": "user"
              }
            }
          ]
        }
      }
    }
  }
}

哪个返回0个文件。

正确的查询是什么，以获取所有文档缺少用户字段？

What is the correct query to get all documents missing the user field?

推荐答案

我发现正确的语法，应该是：

I found the correct syntax, it should have been:

GET /index/type/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "nested": {
            "path": "user",
            "query": {
              "exists": {
                "field": "user"
              }
            }
          }
        }
      ]
    }
  }
}
