ruby – Sunspot：按属性排序/排序facet结果,例如created_at

资产模型：

searchable do
   text @R_632_6964@
   text :description
   time :created_at
   Integer :category_ids,:multiple => true,:references => Category
end

控制器：

search = Asset.search() do
   keywords(h(params[:query]),:fields => [@R_632_6964@,:description])
   faCET(:category_ids)
   order_by :created_at
end

我想对我的方面进行排序：Category_ides not via：count(点击次数).类别应按created_at排序.查看文档构面(：category_ids,：sort =>：count ||：indeX).两种选择都不适合我.

如何解决方面的订单问题？

解决方法

result = Product.solr_search do |s|
  s.keywords params[:q]
  s.faCET :category_id
  s.paginate :per_page => 3,:page => @page
end

faCET_rows = result.faCET(:category_id).rows.sort { |left,right| left.instance.created_at <=> right.instance.created_at }
