潤感通過查詢功能

我有意識的查詢來獲得根據查詢組mimetypeGroup -潤感通過查詢功能

GET /_all/explore/_search 
{ 
    "size": 0, 
    "aggs": { 
    "mimeTypeGroup": { 
     "terms": { 
     "field": "mimeTypeGroup" 
     } 
    } 
    } 
}

我在Java code.I如何執行這個查詢已經在我的Java代碼嘗試這得到結果。我需要的結果是低於added-

client.prepareSearch().setIndices(getIndexNames()).addAggregation(AggregationBuilders.cardinality("mimeTypeGroup").field("mimeTypeGroup")).setTypes("explore").execute().actionGet(ES_TIMEOUT_MS)

但它給我的JSON像 -

    "aggregations": {

      "value": 5

    } 
}

但我想作爲結果 -

{ 
    "took": 18, 
    "timed_out": false, 
    "_shards": { 
     "total": 81, 
     "successful": 81, 
     "failed": 0 
    }, 
    "hits": { 
     "total": 673, 
     "max_score": 0, 
     "hits": [] 
    }, 
    "aggregations": { 
     "mimeTypeGroup": { 
      "doc_count_error_upper_bound": 0, 
      "sum_other_doc_count": 0, 
      "buckets": [ 
       { 
        "key": "miscellaneous", 
        "doc_count": 52 
       }, 
       { 
        "key": "application", 
        "doc_count": 28 
       }, 
       { 
        "key": "text", 
        "doc_count": 6 
       }, 
       { 
        "key": "image", 
        "doc_count": 4 
       }, 
       { 
        "key": "audio", 
        "doc_count": 2 
       } 
      ] 
     } 
    } 
}

的aggregration你做的是基數aggregration ，（您需要使用術語聚合代替）

client.prepareSearch().setIndices(getIndexNames()).addAggregation(
AggregationBuilders.cardinality("mimeTypeGroup").field("mimeTypeGroup") 
).setTypes("explore").execute().actionGet(ES_TIMEOUT_MS)

使用條款聚合獲取條款聚合的響應（如在json中），並使用setSize(0)刪除搜索響應。

client.prepareSearch().setIndices(getIndexNames()).addAggregation(
AggregationBuilders.terms("mimeTypeGroup").field("mimeTypeGroup") 
).setTypes("explore").setSize(0).execute().actionGet(ES_TIMEOUT_MS)
