Elasticsearch8.x分页查询一万条问题

1.修改索引配置

put /emr_outpatient_visit_record/_settings
{
  "index": {
    "max_result_window": 10000000
  }
}

2.Java api 修改 trackTotalHits为true

SearchResponse<JSONObject> response = esClient.search(s -> s
                        .index(indexName)
                        .query(query -> query.bool(bool -> {
                            //姓名查询
                            if (StringUtil.isNotBlank(paramsJSON.getString("xm"))) {
                                bool.must(q -> q.matchPhrase(t -> t.field("name").query(paramsJSON.getString("xm"))));
                            }
                            return bool;
                        }))
                        .from(from)
                        .size(size)
                        .sort(so -> so.field(f -> f.field("hp_date").order(SortOrder.Desc)))
                        .trackTotalHits(t->t.enabled(true))
                , JSONObject.class);
