We are using Spring Data Elasticsearch Reactive Template

Query searchQuery = new NativeSearchQueryBuilder()
                .withQuery(queryBuilder)
                .withPageable(PageRequest.of(0, 10))
                .addAggregation(AggregationBuilders.terms("categories").field("category"))
                .build();

reactiveElasticsearchTemplate.search(searchQuery, documentType, IndexCoordinates.of(indexName))

In response we have Flux<SearchHit<T>> but there are no methods to retrieve aggregations.

How to retrieve the aggregations?

The ReactiveElasticsearchTemplate has aggregate methods.

See the corresponding API interface

There is no combination of the single entities in a flux and the aggregations in the reactive part.
