In contrast to metrics I'd like to use aggregation outputs as an input to filtering for documents in one query. Bucket Size By default, the terms aggregation returns the top ten terms with the most documents. They allow you to calculate metrics, group data into buckets, and gain valuable insights that can help drive decision 2 I'd like to use aggregation outputs as an input to filtering for documents in one query.
