            };

                var lowlevelClient = new ElasticLowLevelClient(settings);
                var ndexResponse = lowlevelClient.Index<BytesResponse>("people", "1", PostData.Serializable(person));
                byte[] responseBytes = ndexResponse.Body;
            }
            catch (Exception ex)
            {}
        }

 可用直接调用 get   http://localhost:9200/people/_search?q=gender:0  搜索也可以出现结果
