ElasticSearch 返回的hits里面获取不到数据

Question

问题描述

想要获取搜索结果中hits的数据，遍历his[]的时候发现为空。不知道是什么原因，es版本6.4.3，client版本6.4.3
使用postman能获取数据。使用restclient，控制台显示如下：但是hits[] 中无内容。
总记录数：3
{"took":2,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":3,"max_score":4.0247,"hits":[]}}
总记录数：3
{"took":5,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":3,"max_score":4.0247,"hits":[]}}

 searchText = "安装出错 pass";
        SearchRequest searchRequest = new SearchRequest(INDEX_NAME);
        searchRequest.types(INDEX_TYPE);
        SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
        sourceBuilder.query(QueryBuilders.multiMatchQuery(searchText,"title","text"));
        sourceBuilder.from(PAGE_STAER);
        sourceBuilder.from(PAGE_SIZE);
        sourceBuilder.sort(new ScoreSortBuilder().order(SortOrder.DESC));
        searchRequest.source(sourceBuilder);

        try {
            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
            SearchHits hits = searchResponse.getHits();
            SearchHit[] searchHits = hits.getHits();
            List<EsSearchDocResponseMessage> tempEntityList = new ArrayList<>();
            for(SearchHit hit : searchHits){
                float score = hit.getScore();
                Map<String,Object> sourceAsMap = hit.getSourceAsMap();
                EsSearchDocResponseMessage tempEntity = new EsSearchDocResponseMessage();
                tempEntity.setScore(score);
                tempEntity.setText((String)sourceAsMap.get("text"));
                tempEntity.setArticleId((String)sourceAsMap.get("articleId"));
            }

Answer 1

        sourceBuilder.from(PAGE_STAER);
        sourceBuilder.from(PAGE_SIZE);

设置了两次from，跳过数据太多了

Answer 2

试试
sourceBuilder.from(PAGE_STAER-1);
sourceBuilder.from(PAGE_SIZE);

分页从0开始吧
