Searchkick仅返回某些值，而不是全部

Question

当使用searchkick执行搜索时，我得到所有字段的结果。我想将响应限制为仅输出某些字段，例如title。

# movie.rb
class Movie < ApplicationRecord
  searchkick autocomplete: ['title']
end

# search_controller.rb
def autocomplete
  render json: Movie.search(params[:query], autocomplete: true, limit: 10, fields: [:title])
end

我的回应还是

[{"id":1,"title":"Megamind","director":"Tom McGrath","genre":"Animation | Action | Comedy","description":"The supervillain Megamind finally defeats his nemesis, the superhero Metro Man. But without a hero, he loses all purpose and must find new meaning to his life.","length":95,"year":2010,"imdb_id":"tt1001526","imdb_rating":"7.3","created_at":"2016-04-16T19:50:24.893Z","updated_at":"2016-04-16T19:50:24.893Z"}]

我正试图只拿回标题。通过阅读不同的问题，我认为这应该与fields我的搜索有关，但这不会改变响应。我也尝试使用_source-attribute，但没有运气。

您可以使用：

select_v2: ["title"], load: false
