            countRequest.types(Constants.VOICE_TYPE_NAME);

            SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
            searchSourceBuilder.query(queryBuilder);

            countRequest.source(searchSourceBuilder);

            CountResponse countResponse = ElasticSearchClientUtil.getRestClient().count(countRequest, RequestOptions.DEFAULT);

            return countResponse!=null?countResponse.getCount():0L;
        }catch (Exception e){
    
            LOGGER.error("数据统计异常 e:{}", ExceptionUtils.getFullStackTrace(e));
        }
