如何在 elasticsearch 中搜索嵌套属性

Question

我的一个弹性索引中有一组记录，我正在尝试通过邮递员执行搜索查询，我当前的查询看起来像这样，应该找到 2 个结果，但结果为零。有什么问题吗？

{
  "query": {
    "match": {
      "vehicle.CAR_WHEEL_DESCRIPTION": "A1=BB=C2C=D35"
    }
  }
}

当前响应：

{
    "took": 6,
    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 0,
            "relation": "eq"
        },
        "max_score": null,
        "hits": []
    }
}

我试过这样做，但我不仅得到了完全匹配，还得到了其他一些，总共 12 条记录（应该是 2，完全匹配记录）

{
  "query": {
    "nested": {
      "path": "vehicle",
      "query": {
        "bool": {
          "must": [
            { "match": { "vehicle.CAR_WHEEL_DESCRIPTION": 
"A1=BB=C2C=D35" } }
          ]
        }
      },
      "score_mode": "avg"
    }
  }
}

这是我根据你的信息做的例子。

PUT teste
{
  "mappings": {
    "properties": {
      "vehicle": {
        "type": "nested",
        "properties": {
          "CAR_WHEEL_DESCRIPTION": {
            "type": "text"
          }
        }
      }
    }
  }
}

POST teste/_doc
{
  "vehicle": {
    "CAR_WHEEL_DESCRIPTION": "A1=BB=C2C=D35"
  }
}

GET teste/_search
{
  "query": {
    "nested": {
      "path": "vehicle",
      "query": {
        "match": {
          "vehicle.CAR_WHEEL_DESCRIPTION": {
            "query": "A1=BB=C2C=D35"
          }
        }
      }
    }
  }
}
