Elasticsearch滚动不起作用

Question

我正在运行以下Elasticsearch聚合查询

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"}}
                    }
                }
            }
        }'

这将按预期返回一个scroll_id，但是当我使用它时，响应为“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":[]}}

好像滚动不适用于聚合。

任何建议将不胜感激。

从滚动的官方文档 ：

如果请求指定聚合，则仅初始搜索响应将包含聚合结果。
