    long docCount = entry.getDocCount();            // Doc count
    logger.info("key [{}]; doc_count [{}]"; key; docCount);

    // We ask for top_hits for each bucket
    TopHits topHits = entry.getAggregations().get("top");
    for (SearchHit hit : topHits.getHits().getHits()) {
        logger.info(" -> id [{}]; _source [{}]"; hit.getId(); hit.getSourceAsString());
