               "userType": {
                  "id": "3",
                  "type": "End User"
               },
               "hobbies": [
                  {
                     "id": "3",
                     "description": "Writing Books"
                  },
                  {
                     "id": "4",
                     "description": "Gardening"
                  }
               ]
            }
         }

这是我的 json 结构，我想获取爱好下的描述为“园艺”的所有记录。

我是 Elasticsearch 新手，如果有人知道请帮助我。

“描述”:“园艺”

这是您的查询:

{
  "query": {
    "nested": {
      "path": "hobbies",
      "query": {
        "match": {
          "hobbies.description": "Gardening"
        }
      }
    }
  }
}
