public static ByteArrayOutputStream printDSL(ElasticsearchTransport transport,
                                                          SearchRequest searchRequest){
    try (ByteArrayOutputStream baos = new ByteArrayOutputStream();

    } catch (Exception e) {
        log.error("print SearchRequest DSL error: {}", e.getMessage(), e);
    }

}

调用方式:

builder.index(indexList).allowNoIndices(true);
SearchRequest searchRequest = builder.build();
SearchResponse response = esClient.search(searchRequest,
        HashMap.class);

EsUtils.printSearchRequestDSL(esClient._transport(), searchRequest)
