【記錄】elasticsearch查詢索引所有數據總數

 

在es中trackTotalHits(true) 可以查詢索引中數據總數

 

SearchSourceBuilder sourceBuilder = new SearchSourceBuilder()
                .from((pageBO.getCurrent()-1) * pageBO.getSize())
                .size(pageBO.getSize())
                .sort("time.keyword", SortOrder.DESC).trackTotalHits(true);
