ES查询总数

{
  "track_total_hits":true,
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "rtype.keyword": "010100"
          }
        },
        {
          "prefix": {
            "incharge_wa_department.keyword": "34"
          }
        }
      ]
    }
  }
}

而要在文档数大于10000时获取实际的数量，需要加入参数：track_total_hits

track_total_hits=true表示显示实际的文档数，此时hits.total的会变成：

java代码

NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withQuery(booleanQuery)
                //排序
                .withSort(SortBuilders.fieldSort(MessageAppAnalyze.CAPTURE_TIME).order(SortOrder.DESC))
                //聚合
                .addAggregation(fasAgg)
                .withPageable(PageRequest.of(0, 10)).build();
        // 搜索，获取结果
        searchQuery.setTrackTotalHits(true);
