arrays - Elasticsearch : Index Mapping for integer array

Question

我为其中一个文档定义了以下索引映射:

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

当我尝试索引以下文档时:

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

我收到以下异常:

从此链接http://www.elasticsearch.org/guide/reference/mapping/array-type/ ，我相信索引映射没有问题。我做错了什么？

当您具有父/子关系时，您需要在为子文档建立索引时指定父文档。请参阅此处的 Elasticsearch 文档:http://www.elasticsearch.org/blog/managing-relations-inside-elasticsearch/您没有说明如何对这些内容建立索引；通过curl，它应该看起来像这样，其中activity-id是这个收藏夹的父文档的id:

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