ES RestHighLevelClient实现分页查询

public Result query() {
        Result result = new Result();
        try {
            SearchRequest searchRequest = new SearchRequest();
            //索引名称
            searchRequest.indices("查询的索引名称");
            SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
			//根据ID进行排序
            sourceBuilder.sort("_id");
            //分页
            sourceBuilder.from(0);
            sourceBuilder.size(100);
            BoolQueryBuilder query = new BoolQueryBuilder();
            sourceBuilder.query(query);

            QueryBuilder queryBuilder = null;
            //各种查询
            queryBuilder = QueryBuilders.matchAllQuery();
            //queryBuilder = QueryBuilders.termQuery("", "");
            //queryBuilder = QueryBuilders.matchQuery("", "");
            //queryBuilder = QueryBuilders.rangeQuery("");
            //queryBuilder = QueryBuilders.existsQuery("");
            //匹配策略
            query.must(queryBuilder);
            //query.mustNot(queryBuilder);
            //query.should(queryBuilder);
            searchRequest.source(sourceBuilder);
            SearchResponse rp = RestHighLevelClient.get().search(searchRequest, RequestOptions.DEFAULT);
            result.setTotal(rp.getHits().getTotalHits());
            if (result.getTotal() > 0) {
                List<RecordInfo> recordInfoList = new ArrayList<>();

            }
        } catch (IOException e) {
            log.error("查询失败", e);
