日付フィールド上ElasticSearch用語集約

Question

私はESにこの要求を送信しています：

{ 
    "aggregations" : { 
    "followUpActivity.metainfo.metainfos.date1" : { 
     "terms" : { 
     "field" : "metainfos.date1", 
     "missing" : "2016-07-20T13:59:06.208Z", 
     "order" : { 
      "_count" : "desc" 
     } 
     } 
    } 
    } 
} 

これが結果です：あなたはmetainfos.date1_ldateは二つの文書、しかしバケツに通知され見ることができるように

      "date1_ldate":[

      ]

     } 
     } 
    ] 
    }, 
    "aggregations":{ 
    "followUpActivity.metainfo.metainfos.date1":{ 
     "doc_count_error_upper_bound":0, 
     "sum_other_doc_count":0, 
     "buckets":[ 

     ] 
    } 
    } 
} 

結果は空です。

私は間違っていますか？

Answer 1

フィールド名がdate1_ldateないdate1です。だから、"terms" : { "field" : "metainfos.date1_ldate"が必要です。
