c# - 建议完成嵌套的用法

Question

我正在尝试对某个位置(国家和城市)进行“SuggestCompletion”查询，我想对这两个字段执行查询。

到目前为止，我的映射如下:

var response =  _client.CreateIndex(PlatformConfiguration.LocationIndexName,
                    descriptor => descriptor.AddMapping<LocationInfo>(
                        m => m.Properties(
                            p => p.Completion(s => s
                                .Name(n=>n.CountryName)
                                .IndexAnalyzer("simple")
                                .SearchAnalyzer("simple")
                                .MaxInputLength(50)
                                .Payloads()
                                .PreserveSeparators()
                                .PreservePositionIncrements()).
                                Completion(s=>s.Name(n => n.City)
                                .IndexAnalyzer("simple")
                                .SearchAnalyzer("simple")
                                .MaxInputLength(50)
                                .Payloads()
                                .PreserveSeparators()
                                .PreservePositionIncrements())
                            )));

我如何索引元素:

public bool IndexLocations(IList<LocationInfo> locations)

        {
            var bulkParams = locations.Select(p => new BulkParameters<LocationInfo>(p){
                Id = p.Id, 
                Timestamp = DateTime.Now.ToTimeStamp()
            });
            var response = _client.IndexMany(bulkParams, PlatformConfiguration.LocationIndexName);
            return response.IsValid;
        }

查看映射后，我将查询更改为以下内容:

var response = _client.Search<LocationInfo>(location =>
                location.Index(PlatformConfiguration.LocationIndexName).
                    SuggestCompletion("locationinfo", f => f.OnField("countryName").Text(text).Size(1)));

我也尝试过:

 var response = _client.Search<LocationInfo>(location =>
                location.Index(PlatformConfiguration.LocationIndexName).
                    SuggestCompletion("countryName", f => f.OnField("countryName").Text(text).Size(1)));  

.....我仍然得到一个空结果

IndexMany()中已删除对带有包装的BulkParameters的NEST 1.0.0 beta 1的支持

如果要使用具有更高级参数的批量，现在必须使用Bulk()命令。

遗憾的是，该Beta仍与BulkParameters类in the assembly一起提供

此后已在开发分支中删除。

所以现在发生的事情是您实际上是在索引"bulkparameters``1``"类型的文档，而不是"locationinfo"。因此，为"locationinfo"指定的映射不起作用。

有关在为单个项目配置高级参数时如何使用Bulk()一次索引许多对象的信息，请参见here for an example。
