You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: articles_controller.rb
    path of file: ./repos/forem/app/controllers/concerns/api
    
    the code of the file until where you have to start completion: module Api
  module ArticlesController
    extend ActiveSupport::Concern

    INDEX_ATTRIBUTES_FOR_SERIALIZATION = %i[
      id user_id organization_id collection_id
      title description main_image published_at crossposted_at social_image
      cached_tag_list slug path canonical_url comments_count
      public_reactions_count created_at edited_at last_comment_at published
      updated_at video_thumbnail_u
    
    def search
      # I temporarily added a new search endpoint in the interest of getting the chatGPT plugin live without changing
      # the existing index endpoint. There are some experiments which we want to conduct which I think makes sense on
      # a new endpoint rather than an existing one. We may want to refactor the index one in the future.
      @articles = Articles::ApiSearchQuery.call(params)

      # This adds some inconsistency where we omit the body markdown when the response has more than 1 article because
      # ChatGPT cannot process the long body request.
      @articles = if @articles.count > 1
                    @articles.select(INDEX_ATTRIBUTES_FOR_SERIALIZATION).decorate
                  else
                    @articles.select(ADDITIONAL_SEARCH_ATTRIBUTES_FOR_SERIALIZATION).decorate
                  end
