RavenDB动态查询

Question

我收到错误：

System.InvalidOperationException occurred
  HResult=-2146233079
  Message=There is no index named: dynamic/Routes
  Source=Raven.Client.Lightweight
  StackTrace:

       at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
       at Cwm.ReadModel.Users.UserEventsHandler.UpdateRoutes(User u)
  InnerException: 

运行简单查询

 session.Query<Route>().Where(r => r.User.Id == u.Id).ToList().ForEach(r => r.User = u);

如何修复/解决此问题？
