Thinking Sphinx 在所有模型中搜索搜索：每个模型的结果数

Question

我进行了全局搜索（涵盖所有模型）。现在，我想知道每个模型可以有多少结果。

例如，如果我的搜索返回 10 行/结果并且我有 3 个模型，是否可以知道模型 A 有 3 个，模型 B 有 2 个，模型 C 有 5 个结果？我想用它来创建图表。

   :star => true, 
   :with     => filters, 
   :conditions =>  { :ending_time =>  params[:ending_time], :starting_time =>  params[:starting_time]},
   :page     => params[:page],
   :per_page => 20 

 puts facets[:sphinx_internal_class]

嗯，你总是可以从搜索结果中计算出来的：

search = ThinkingSphinx.search params[:query]
groups = search.group_by(&:class)
groups.each { |klass, results| puts klass.name, results.length }

但是，如果您获得的结果数量大于页面大小，那么这将不起作用。更好的方法是使用构面调用：

facets = ThinkingSphinx.facets params[:query] # takes same arguments as search
facets[:sphinx_internal_class]
