思考狮身人面像的结果基于模型偏好(Thinking sphinx results based on model preference)

 我有两个模型：'A'和'B'，并且想要使用Thinking sphinx搜索两个模型中的对象，但我想要所有模型'A'的结果然后'B'。 我怎样才能做到这一点？ 我将以下选项传递给sphinx查询 
 
{:match_mode=>:extended, :sort_mode=>:extended, :star=>true, :order=>"@relevance DESC", :ignore_errors=>true, :populate=>true, :per_page=>10, :retry_stale=>true, :classes => [A,B]}
 
 然后使用以下方法获取搜索结果 
 
ThinkingSphinx.search "*xy*", options
 
 但它给出了混合排序的结果，而我首先需要所有'A'对象。 我怎样才能做到这一点？ 

I have two models: 'A' and 'B', and want to search objects from both of them using Thinking sphinx, but I want all results of model 'A' first and then 'B'. How can I do that? I pass the following options to sphinx query
 
{:match_mode=>:extended, :sort_mode=>:extended, :star=>true, :order=>"@relevance DESC", :ignore_errors=>true, :populate=>true, :per_page=>10, :retry_stale=>true, :classes => [A,B]}
 
And then get search results using:
 
ThinkingSphinx.search "*xy*", options
 
But it gives results in mixed ordering, whereas I need all 'A' objects first. How can I do that?
