java restHighLevelClient 客户端使用_id排序使得查询变慢

 1   MultiSearchRequest request = new MultiSearchRequest();
 2         SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
 3         searchSourceBuilder.from(pageable.getPageNumber() * pageable.getPageSize());
 4         searchSourceBuilder.size(pageable.getPageSize());
　　　　　　　// 客户端构造查询语句使用元数据id排序使得查询变慢10倍
 5

searchSourceBuilder.sort("cTime", SortOrder.DESC);

　　改为其他字段解决

 6         searchSourceBuilder.query(boolQueryBuilder);
 7         SearchRequest firstSearchRequest = new SearchRequest();
 8         firstSearchRequest.source(searchSourceBuilder);
 9         firstSearchRequest.indices("comment");
10         request.add(firstSearchRequest);
11         CountRequest countRequest = new CountRequest();
12         countRequest.query(boolQueryBuilder);
13         countRequest.indices("comment");
14         CountResponse count = null;
15         List<CommentBO> datalist = new LinkedList<>();
16         try {
17             long esStartTime = System.currentTimeMillis();
18             log.info("es查询开始时间：{}", esStartTime);
19             MultiSearchResponse response = restHighLevelClient.msearch(request, RequestOptions.DEFAULT);
