Elasticsearch滾動不起作用

Question

我正在運行以下Elasticsearch聚合查詢

curl -XPOST 'http://localhost:9200/ae2015/_search/?scroll=1m' -d '{
            "size" : 0,
            "query":{"constant_score":{"filter": {"geo_bounding_box" : {"location": {"top_left" : [-180, 85],"bottom_right" : [180, -85]}}}}},
            "aggs":{
                "grid": {
                    "geohash_grid": {"field":"location","precision": 3},
                    "aggs": {
                        "count":{"sum":{"field":"count"}}
                    }
                }
            }
        }'

這將按預期返回一個scroll_id，但是當我使用它時，響應為“空”，即

{"_scroll_id":"xxx","took":936,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":13238893,"max_score":0.0,"hits":[]}}

好像滾動不適用於聚合。

任何建議將不勝感激。

從滾動的官方文檔 ：

如果請求指定聚合，則僅初始搜索響應將包含聚合結果。
