查询未分析嵌套值elasticsearch

Question

我是elasticsearch的新手，并且很难在嵌套对象中查询->leftjoin('k.personToKey', 'ptk') 字段。这是我的映射（我在谈论'not_analyzed'字段）：

"subscriptions.entity_type"

这是一个示例条目：

{
   "app": {
      "mappings": {
         "user_subscriptions": {
            "properties": {
               "subscriptions": {
                  "type": "nested",
                  "properties": {
                     "entity_id": {
                        "type": "integer"
                     },
                     "entity_type": {
                        "type": "string",
                        "index": "not_analyzed"
                     },
                     "event_name": {
                        "type": "string"
                     }
                  }
               },
               "test": {
                  "type": "string",
                  "index": "not_analyzed"
               }
            }
         }
      }
   }
}

在尝试使用精确值查询{ "took": 1, "timed_out": false, "_shards": { "total": 1, "successful": 1, "failed": 0 }, "hits": { "total": 1, "max_score": 1, "hits": [ { "_index": "app", "_type": "user_subscriptions", "_id": "12", "_score": 1, "_source": { "test": "DevCommunityBundle:Topic", "subscriptions": [ { "entity_type": "DevCommunityBundle:Topic", "entity_id": 3, "event_name": "test" } ] } } ] } } 字段时，我会得到预期的结果，但是，当我尝试使用相同的确切值查询"test"时，我得不到任何结果。
