Bucket Sort Aggregation

The BucketSort aggregation is a parent pipeline aggregation which sorts the buckets of its parent multi-bucket aggregation. Zero or more sort fields may be specified together with the corresponding sort order.

To create a BucketSort aggregation do the following:

import zio.elasticsearch.aggregation.BucketSortAggregation
import zio.elasticsearch.ElasticAggregation.bucketSortAggregation

val aggregation: BucketSortAggregation = bucketSortAggregation(name = "aggregationSort")

If you want to change the from, you can use from method:

val aggregationWithFrom: BucketSortAggregation = bucketSortAggregation(name = "aggregationSort").from(5)

If you want to change the size, you can use size method:

val aggregationWithSize: BucketSortAggregation = bucketSortAggregation(name = "aggregationSort").size(5)

If you want to change the sort, you can use sort method:

import zio.elasticsearch.query.sort.SortByField.{byCount, byKey}

val aggregationWithSort: BucketSortAggregation = bucketSortAggregation(name = "aggregationSort").sort(byCount, byKey)

If you want to add aggregation (on the same level), you can use withAgg method:

val multipleAggregations: MultipleAggregations = bucketSortAggregation(name = "aggregationSort").withAgg(maxAggregation(name = "maxAggregation", field = Document.doubleField))
