Problems to search ActsAsTaggableOn with sunspot

Question

I've setup sunspot and I'm searching fine in my Place.name field

Now I want to search by "acts as taggable" tags

I've setup two contexts to taggable, categories

with this model and controller I'm not getting any errors but when I search for my tag name sunspot doesn't return any results.

I've run rake sunspot:reindex and rake sunspot:solr:reindex but no change.

When I run Place.last.categories in rails console I only get one array ["Category one","Category 2"]

Model

class Place < ActiveRecord::Base
  extend FriendlyId
  friendly_id :name, use: :slugged

  searchable :auto_index => true, :auto_remove => true  do
    text :name, :stored => true
    string :category_list, :multiple => true, :stored => true
  end


  acts_as_votable   
  acts_as_mappable :default_units => :kms,
                   :lat_column_name => :latitude,
                   :lng_column_name => :longitude


  validates_presence_of :name , :state, :city, :neighborhood, :adress,:latitude, :longitude

  belongs_to :user

  acts_as_ordered_taggable_on :categories, :obstacles



end

Controller

class PlacesController < ApplicationController
  before_action :set_place, only: [:show, :edit, :update, :destroy, :upvote, :downvote, :favorite]
  before_action :authenticate_user!, except: [:index, :show]

  # GET /places
  # GET /places.json
  def index
    @search = Place.search do
      fulltext params[:search]
    end  
    @places = @search.results
  end

In this case you should add searchable block in your tag model.In my memory,the tag model may have assoiations,if you want to know more about how to index Rails associations,you may checkout this
