ThinkingSphinx：使用BatchedSearch时查看结果权重？

Question

在ThiningSphinx v3上，如何结合BatchedSearch检索搜索结果权重？

我使用了here所描述的BatchedSearch：

batch = ThinkingSphinx::BatchedSearch.new
batch.searches << Article.search('foo', :select => '*, weight()')
batch.searches << Article.search(:conditions => {:name => 'bar'}, :select => '*, weight()')
batch.searches << Article.search_for_ids('baz', :select => '*, weight()')
batch.populate
res = batch.searches #=> [[foo results], [bar results], [baz results]]

在这3个搜索结果集中的每一个中，我想访问Result Weights，但似乎只能通过单个搜索对象访问权重？在上面的代码块之后，我试过了：

res.each do |w|
 w.context[:panes] << ThinkingSphinx::Panes::WeightPane
end

res.first.first #is a valid search result

res.first.first.weight
#returns error: 
#<NoMethodError: undefined method `weight' for #<Work:0xb2a9a648>>

您需要在填充结果之前将窗格添加到每个搜索对象。所以，请尝试以下方法：

batch = ThinkingSphinx::BatchedSearch.new
batch.searches << Article.search('foo', :select => '*, weight()')
batch.searches << Article.search(:conditions => {:name => 'bar'}, :select => '*, weight()')
batch.searches << Article.search_for_ids('baz', :select => '*, weight()')
batch.searches.each do |search|
  search.context[:panes] << ThinkingSphinx::Panes::WeightPane
end
batch.populate

res = batch.searches
res.first.first.weight
