在elasticsearch中获取第N页数据进行复合聚合的正确方法是什么?
What is the correct way to get Nth page's datas for composite aggregation in elasticsearch?
We can do pagination for composite aggregation using with "After"。但是,当我们使用 "After" 时,它只会给我们下一页。如何直接获取第N页或上一页的数据?
GET /_search
{
"aggs" : {
"my_buckets": {
"composite" : {
"size": 2,
"sources" : [
{ "date": { "date_histogram": { "field": "timestamp", "calendar_interval": "1d", "order": "desc" } } },
{ "product": { "terms": {"field": "product", "order": "asc" } } }
],
"after": { "date": 1494288000000, "product": "mad max" }
}
}
}
}
不,不能直接请求特定页面,您需要分页,直到到达您需要的 "page"。
