如何在RavenDB中选择一种类型的所有文档

到目前为止,我尝试了以下方法:

public class Widget
{
    public int Id;
    public string Name;
}

public static class Main
{
    public static void Main()
    {
        // Initialize store and preload with widgets...

        using (var session = store.OpenSession())
        {
            var widgets = session.Load<Widget>();
            foreach(var widget in widgets)
            {
                Console.WriteLine(widget.Name);
            }
        }
    }
}

通过添加索引,然后将该索引用作查询,我可以加载所有内容:

var store = new DocumentStore();
store.DatabaseCommands.PutIndex("AllWidgets", new IndexDefinition<Widget>
{
    Map = widget => from widget in widgets
                   select new { widget }
});

// Back in Main
var widgets = session.Query<Widget>("AllWidgets");
// Do stuff with widgets.

有没有一种方法可以直接获取所有类型的文档 Widget
