ruby-on-rails - Tire + Elasticsearch:如何搜索值范围？

Question

到目前为止，您一直很喜欢Tyre和elasticsearch，但无法弄清楚如何在以下范围之间搜索值:

age_from age_to

18至20

并返回年龄在这两个范围之间的所有配置文件？
我有一个整数列Profile.age

到目前为止功能不完整

def self.search(params)

    #, default_operator: "AND
    tire.search(load: true, page: params[:page], per_page: 20) do
      query do
        should { string params[:query] } if params[:query].present?
        should { integer age_to[:age_to] } if params[:age_to].present?
      end
      to_curl
    end

  end

Answer 1

query do
    should { string params[:query] } if params[:query].present?
    should { range :age, { gte: params[:age_from], lte: params[:age_to] } } if params[:age_to].present? && params[:age_from].present?
end
