elasticSearch 简单的分页查询

        SearchRequest request = new SearchRequest();
        request.indices("user");
        SearchSourceBuilder builder = new SearchSourceBuilder().query( QueryBuilders.matchAllQuery() );

        //从文档索引0开始
        //(当前页码 - 1 ) * 每页显示条数
        builder.from(0);
        builder.size(3);//取三个数据

        request.source(builder);

        SearchResponse response = client.search( request, RequestOptions.DEFAULT );

        SearchHits hits = response.getHits();

        System.out.println(hits.getTotalHits());
        System.out.println(response.getTook());
