弹性搜索 - 聚合分页

Question

我有一个索引，我查询聚合，而不是立即返回整个聚合我想让它以块的形式返回，即小块，是否有可能在弹性搜索中这样做？

Answer 1

尝试使用Bucket sort

POST /sales/_search
{
    "size": 0,
    "aggs" : {
        "sales_per_month" : {
            "date_histogram" : {
                "field" : "date",
                "interval" : "month"
            },
            "aggs": {
                "total_sales": {
                    "sum": {
                        "field": "price"
                    }
                },
                "sales_bucket_sort": {
                    "bucket_sort": {
                        "sort": [
                          {"total_sales": {"order": "desc"}}
                        ],
                        "size": 3,
                        "from": 10
                    }
                }
            }
        }
    }
}
