ServerError：400类型：search_phase_execution_exception原因：“所有分片均失败”

Question

我正在将Elasticsearch与.net core 2.1一起使用，并且具有以下用于搜索的代码，

  var Buildingpoints= _elasticClient.Search<ElasticSearchModel>(
                     s => s.From(0).Size(600).Query(query => query.Bool(b => b
                     .Filter(filter => filter
                    .GeoDistance(geo => geo
                   .Field(f => f.Location)
                   .Distance(4.0, Nest.DistanceUnit.Kilometers)
                   .Location(41.23, 69.32)
                    ))                                 
                 )
               ));

但是我得到这样的错误 {ServerError：400Type：search_phase_execution_exception原因：“所有分片失败”} 我的索引代码是这样的：

var result = query.Skip(h.PageSize * (h.CurrentPage - 1))
                                  .Take(h.PageSize)
                                  .AsEnumerable()
                                  .Select(a =>
                                  {
                                      var building = a.MapTo<ElasticSearchModel>();
                                      building.Location= new GeoLocation(Convert.ToDouble(a.Latitude), Convert.ToDouble(a.Longitude));
                                      building.LoadEntity(a);
                                      return building;
                                  });

                var searchResult = new SearchResult
                {

                    Building = result,
                    TotalCount = totalCount
                };

                foreach (var post in searchResult.Building)

                {
                    await _elasticClient.IndexDocumentAsync(post);
                }

                return Ok($" {searchResult.TotalCount} building(s) reindexed");
            }

，索引结果为：

我如何更改索引代码以保存位置，或者我对索引有另一个问题？ 请帮助我解决我在Elasticsearch中刚遇到的这个问题，而我已经失去了很多天的解决方案。
