如何限制发送给Algolia的记录？

Question

在Ruby中使用Algolia on Rails的，我可以很容易地指数模型：

class Service < ActiveRecord::Base 
    include AlgoliaSearch 

    algoliasearch per_environment: true do 
    attributesToIndex ['name', 'canonical_url'] 
    attributes ['name', 'canonical_url] 
    add_attribute :type do 
     "Service" 
    end 
    end 
end 

是否有某种方式来限制哪些Service我要送？

例如：Only index Services where name != nil

这是绝对有可能做到： https://github.com/algolia/algoliasearch-rails#restrict-indexing-to-a-subset-of-your-data

class Service < ActiveRecord::Base 
    include AlgoliaSearch 

    algoliasearch if: :name? do 
    end 

end
