Hi. I'm having such kind of problem on defining composite aggregation for paginating the results.

```auto
CompositeAggregationBuilder aggregationBuilder = AggregationBuilders
                    .composite(aggrField, List.of(new TermsValuesSourceBuilder(aggrField).field(aggrField)))
                    .aggregateAfter(Map.of("keyword", aggrField))
                    .size(bucketListInfo.getTopResultsCount());
            searchSourceBuilder
                    .from(paginatedRequestInfo.from())
                    .size(paginatedRequestInfo.size())
                    .aggregation(aggregationBuilder);

final SearchRequest searchRequest = new SearchRequest(bucketListInfo.getIndexName())
                .source(searchSourceBuilder);
        try {
            final SearchResponse response = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
            return extractBucketsFromResponse1(bucketListInfo, response);
        } catch (Exception e) {
            log.error(e.getMessage(), e);
            return null;
        }

```

and this is the [extractBucketsFromResponse1] method definition.

```auto
    private static BucketList extractBucketsFromResponse1(final BucketListInfo bucketListInfo, final SearchResponse response) {
        final BucketList bucketList = new BucketList();
        for (String aggrField : bucketListInfo.getAggrFieldList()) {
            ParsedComposite terms = response.getAggregations().get(aggrField);
            bucketList.getParsedBuckets().add(terms.getBuckets());
        }
        return bucketList;
    }

```

And when getting the results this way, the pagination doesn't work, it gives the wrong result.  
Can anybody please help me on this issue.
