Elasticsearch count buckets

Multi-bucket aggregations are about taking those documents and putting them into buckets—like the group of documents matching each tag. Then, for each bucket, you’ll get one or more numbers that describe the bucket, such as counting the number of groups for each tag. So far you’ve run metrics aggregations on all documents matching the query.. es java 聚合查询获取bucket. 2021-02-28 17:56:57.

Bucket aggregations edit. Bucket aggregations. Bucket aggregations don’t calculate metrics over fields like the metrics aggregations do, but instead, they create buckets of documents.
