Gem 请教一个 Sunspot 配合 Mongoid 出现问题

在仿照 Ruby-China 的实现写一个搜索的功能，现是添加了 base_model 里的 find_in_batches 才终于能执行rake sunspot:reindex

但是@search = Topic.search这里总是会提示错误

Mongoid::Errors::InvalidFind in SearchController#index
Calling Document#find with nil is invalid

似乎是跟 Mongoid 的什么冲突了，改成Topic.solr_search似乎是可以了，尝试：

r = Topic.solr_search { fulltext 'test' }
results = r.results

又是错误...

NoMethodError: undefined method 'id' for #<Array xxxx>

这里 Ruby-China 是怎么解决的？能否简单解释一下... 先谢谢啦

详细的错误代码：
