Tire gemを介してElasticsearchでアタッチメント タイプのインデックスを作成するのが困難です。アタッチメントを正しくセットできません。type

Tire gem から参照されたActiveModel Integration の例を取り上げ、フィールド を追加filenameして、レコードでインデックスを作成するローカル ファイルシステム上の PDF の名前を参照しました。

#app/models/article.rb
class Article < ActiveRecord::Base
  include Tire::Model::Search
  include Tire::Model::Callbacks

  attr_accessible :title, :content, :published_on, :filename

  mapping do
    indexes :id, :type =>'integer'
    indexes :title
    indexes :content
    indexes :published_on, :type => 'date'
    indexes :attachment, :type => 'attachment' 
  end

  def to_indexed_json
    to_json(:methods => [:attachment])
  end

  def attachment
    if filename.present?
       path_to_pdf = "/Volumes/Disk41402/test_proj/sample_pdfs/#{filename}.pdf"
       Base64.encode64(open(path_to_pdf) { |pdf| pdf.read })
    end
  end
end

FWIW - PDF がインデックスに追加されたようです:

$ curl -XGET 'http://localhost:9200/articles/_all/2?pretty=true'  
{
  "_index" : "articles",
  "_type" : "article",
  "_id" : "2",
  "_version" : 1,
  "exists" : true, "_source" : {"content":"Consectetur adipisicing elit, sed do eiusmod tempor incididunt. working?","created_at":"2012-06-21T17:19:03Z","filename":"sample2","id":2,"published_on":"2012-06-20","title":"Two","updated_at":"2012-06-28T00:00:59Z","attachment":"JVBERi0xLjMKJcTl8uXrp/Og0MTGCjQgMCBvYmoKPDwgL0xlbmd0aCA1IDAg\nUiAvRmlsdG...  ... ...4+CnN0YXJ0eHJlZgo4\nNTAzCiUVPRgo=\n"
}
}

しかし、添付ファイルの種類はまだ"type" : "string"あるべきときです"type" : "attachment"

$ curl -XGET 'http://localhost:9200/articles/_mapping?pretty=true'
{
  "articles" : {
    "article" : {
      "properties" : {
        "attachment" : {
          "type" : "string"
        },
        "content" : {
          "type" : "string"
        },
        "created_at" : {
          "type" : "date",
          "format" : "dateOptionalTime"
        },
        "filename" : {
          "type" : "string"
        },
        "id" : {
          "type" : "long"
        },
        "published_on" : {
          "type" : "date",
          "format" : "dateOptionalTime"
        },
        "title" : {
          "type" : "string"
        },
        "updated_at" : {
          "type" : "date",
          "format" : "dateOptionalTime"
        }
      }
    }
  }
}

インデックスを再構築しようとしましたrake environment tire:import CLASS=Article FORCE=trueが、型は文字列のままです。私が台無しにしているところを見た人はいますか？
