最好的方法是使用分区根据文档：GET /_search{ "size": 0, "aggs": { "expired_sessions": { "terms": { "field": "account_id", "include": { "partition": 1, "num_partitions": 25 }, "size": 20, "order": { "last_access": "asc" } }, "aggs": { "last_access": { "max": { "field": "access_date" } } } } }}https://www.elastic.co/guide/en/elasticsearch/reference/6.8/search-aggregations-bucket-terms-aggregation.html#_filtering_values_with_partitions

如果你想向下舍入时间，请使用time.Truncate：
t := time.Now()
fmt.Println(t.Truncate(5*time.Second))
将此应用到您的需求：
// returns in UTC timezone - regardless of input timezone
func getWindow(t time.Time, windowLength time.Duration, step int64) time.Time {
return t.UTC().Truncate(windowLength).Add(
time.Duration(step) * windowLength,
)
}
// time.Now() may be in any timezone - but UTC will be returned (see above)
func GetWindow(windowLength time.Duration, step int64) time.Time {
return getWindow(time.Now(), windowLength, step)
}
