模型的 class 的 Searchkick 聚合

Question

我的 searchkick 实现跨多个索引进行搜索。 它看起来像这样：

@results = Searchkick.search(
  params[:query],
  index_name: [Actors, Producers, Directors],
  fields: ["name"],
  indices_boost: {Actors => 4, Producers => 8, Directors => 2},
  page: params[:page],
  per_page: cookies[:per_page]
  )

如何实现聚合，以便可以根据 class（演员、制片人、导演）过滤结果？

Answer 1

我可以通过将以下 search_data 添加到我的 model 来解决此问题。

def search_data
 {
   name: name,
   class_name: self.class.name
 }
end

然后将 controller 更新为：

@results = Searchkick.search(
  params[:query],
  index_name: [Actors, Producers, Directors],
  fields: ["name"],
  indices_boost: {Actors => 4, Producers => 8, Directors => 2},
  aggs: {class_name:{}},
  page: params[:page],
  per_page: cookies[:per_page]
  )
