Elasticsearch：整數數組的索引映射

Question

我為其中一個文檔定義了以下索引映射：

{
   "favorites":{
      "_parent":{
         "type":"activities"
      },
      "properties":{
         "favorite_count":{
            "type":"integer"
         },
         "details":{
            "type":"integer",
            "store":"yes"
         }
      }
   }
}

當我嘗試索引以下文檔時：

{
      "favorite_count":3,
      "details":[
          1, 25, 4
      ]
}

我得到以下異常：

通過此鏈接http://www.elasticsearch.org/guide/reference/mapping/array-type/ ，我相信索引映射沒有問題。 我究竟做錯了什么？

Answer 1

如果您具有父/子關系，則在索引子文檔時需要指定父項。 請參閱此處的Elasticsearch文檔： http ://www.elasticsearch.org/blog/managing-relations-inside-elasticsearch/您沒有說過如何索引這些文件； 通過curl它應該看起來像這樣，其中activity-id是此收藏夾的父文檔的ID：

curl -XPOST localhost:9200/favorites?parent=activity-id -d'
{
      "favorite_count":3,
      "details":[
          1, 25, 4
      ]
}'

Answer 2

問題已解決。 我在其余api URL中給索引類型名稱錯誤，應該是'localhost：9200 / test-app / favorites / _mapping'；我給它的名稱是localhost：9200 / test-app / ratings / _mapping。
