pg search gem在Heroku上不起作用

Question

I have problem with properly work pg_search gem on Heroku. On localhost works great, but when I try to search some expression on developer site always display empty result. I tried to inspect object of result, but nothing showed. In heroku console comand PgSearch.multisearch("ruby") working fine.

vocabulary.rb

# == Schema Information
#
# Table name: vocabularies
#
#  id         :integer          not null, primary key
#  expression :string
#  meaning    :string
#  created_at :datetime         not null
#  updated_at :datetime         not null
#

class Vocabulary < ActiveRecord::Base
  include PgSearch
  multisearchable :against => [:expression, :meaning]
  belongs_to :user
  validates :expression, :meaning, presence: true
  default_scope -> { order(updated_at: :desc)}
end

VocabulariesController

class VocabulariesController < ApplicationController
  def search
    if params[:search].present?
      @pg_search_documents = PgSearch.multisearch(params[:search]).paginate(:page => params[:page], :per_page => 4)
    else
      @pg_search_documents = Vocabulary.all
    end
  end
end

View:

.searchbar_min
  =render 'layouts/searchbar'
%table.table.table-striped
  %thead
    %tr
      %th Wyrażenie
      %th Znaczenie
      %th
      %th
      %th

  %tbody
    = will_paginate @pg_search_documents
    - @pg_search_documents.each do |pg_search_document|
      %tr
        =pg_search_document.inspect
        %td= pg_search_document.searchable.expression
        %td= HTML_Truncator.truncate(pg_search_document.searchable.meaning, 40).html_safe
        %td
          = link_to vocabulary_path(pg_search_document), class: "btn btn-link" do
            %i.glyphicon.glyphicon-eye-open
            Pokaż
        -if current_user && current_user.admin?
          %td
            = link_to edit_vocabulary_path(pg_search_document), class: "btn btn-link" do
              %i.glyphicon.glyphicon-edit
              Edytuj
          %td
            = link_to vocabulary_path(pg_search_document), :method => :delete, :data => { :confirm => 'Jesteś pewny/a?' }, class: "btn btn-link" do
              %i.glyphicon.glyphicon-trash
              Usuń
%br
  = will_paginate @pg_search_documents

您应该在Heroku控制台中编写： rake pg_search:multisearch:rebuild[Vocabulary]有关更多信息，请检查以下内容： 重建给定类的搜索文档
