es 5.x 版本使用srcoll scan解决数据太大，分页报错的问题

 @Override
    public Page<RealTimeMonitorDomain> querySimlarInfoList(int pageSize, int page, String groupId,String id) {
        //1.初始化条件
        NativeSearchQueryBuilder nsb = new NativeSearchQueryBuilder();//总的查询条件
        BoolQueryBuilder bools = QueryBuilders.boolQuery();
        //2.设置查询
        bools.must(QueryBuilders.termQuery("groupId",groupId));
        bools.mustNot(QueryBuilders.termQuery("id",id));
        nsb.withQuery(bools);
        //3.设置排序
        nsb.withSort(new FieldSortBuilder("pubDate").order(SortOrder.DESC));
        //4.设置分页
        nsb.withPageable(new PageRequest(page-1, pageSize));//pagenum是从0开始，坑爹啊！
        //5.查询的建立
        SearchQuery searchQuery = nsb.build();//查询建立
        logger.info("相似度列表查询sql:"+searchQuery.getQuery().toString());
