Spring ElasticsearchTemplate 經緯度按距離排序

es實體，用 @GeoPointField 註解，值爲：中間逗號隔開，如 29.477000,119.278536（經度, 維度）

@Document(indexName = "v_intelligent_store")
@Data
public class IntelligentStore implements Serializable {
  private String id;

  /** 體驗店名稱 */
  private String name;
  /** 聯繫人姓名 */
  private String contactsName;
  /** 聯繫手機號 */
  private String phoneNumber;
  /** 聯繫電話 */
  private String telePhone;
  /** 場景分類 */
  private String category;
  /** 開店時間 */
  private LocalDate foundTime;
  /** 營業時間 */
  private String openHours;
  /** 主營產品 */
  private String mainProduct;
  /** 店鋪面積 */
  private Double shopSize;
  /** xx省xx市xx區 */
  private String area;
  /** 店鋪面積 */
  private String detailAddress;
  /** 經維度，中間逗號隔開 */
  @GeoPointField private String location;
  ...  
}

接口：

/**
   * 搜索附近的體驗店
   *
   * @param lat 經度
   * @param lon 維度
   * @param distance 距離
   * @param pageable
   * @return
   */
  Page<IntelligentStoreDTO> findAllByLocaltion(
      double lat, double lon, double distance, Pageable pageable);

實現：

@Override
  public Page<IntelligentStoreDTO> findAllByLocaltion(
      double lat, double lon, double distance, Pageable pageable) {

    GeoDistanceQueryBuilder builder =
        QueryBuilders.geoDistanceQuery("location")//查詢字段
            .point(lat, lon)//設置經緯度
            .distance(distance, DistanceUnit.METERS)//設置距離和單位（米）
            .geoDistance(GeoDistance.ARC);
    GeoDistanceSortBuilder sortBuilder =
        SortBuilders.geoDistanceSort("location")
            .point(lat, lon)
            .unit(DistanceUnit.METERS)
            .order(SortOrder.ASC);//排序方式
    //構造查詢條件
    NativeSearchQueryBuilder nativeSearchQueryBuilder =
        new NativeSearchQueryBuilder()
            .withFilter(builder)
            .withSort(sortBuilder)
            .withPageable(pageable);

    Page<IntelligentStoreDTO> page =
        elasticsearchTemplate.queryForPage(
            nativeSearchQueryBuilder.build(), IntelligentStoreDTO.class);
    return page;
  }

查詢10千米範圍數據，返回：
