使用以下代码添加地理数据

jedis.geoadd("storegeodata", 51.5074, 0.1278, "London");
//while member string is mostly json 
jedis.geoadd("storegeodata", 51.5074, 0.1278, "{place: London}");
jedis.geoadd("storegeodata", 51.5074, 0.1278, "{place: London, lat: 51.5074, lon: 0.1278}");

当geohash由于成员字符串不同而被复制时，如何检索基于geohash的唯一值以避免冗余

public Map<String, Object> checkRedisGeo(double lat, double lon, Jedis j) {
    Map<String, Object> result = new HashMap<>();
    try
    {
        GeoRadiusParam param = GeoRadiusParam.geoRadiusParam();
        param.sortAscending();
        param.withDist();
        param.count(1);
        System.out.println("lat :"+lat+" , lon :"+lon);
        List<GeoRadiusResponse> response =  j.georadius("commander",
                lon,lat, 150, GeoUnit.M, param);    
        //System.out.println(response.size()+" size");
      if(response.size() > 0)
      {
          for (GeoRadiusResponse geoRadiusResponse : response) {
                System.out.println("lat :"+lat+" , lon :"+lon+",  stringmember :"+geoRadiusResponse.getMemberByString());
                //System.out.println(geoRadiusResponse.getDistance());
                Object[] data= {geoRadiusResponse.getMemberByString()};
                System.out.println(data);
                result.put("result", data);
               }
      }else {
         // sendEvents(streamEvent, null, streamEventChunk);
          System.out.println("E");
      }
    } catch (Exception e) {
        LOGGER.error("checkRedisGeo err : "+e);
    }
  return result;
}

哪个检索结果但如何根据geohash/score值过滤掉，如何得到所有不同的分数？
