Index help on Polymorphic Associations

Hello,

I'm a newbie to aaf and rails and I hope anyone can help me with this.
I have the following Models:

class Project < ActiveRecord::Base
  acts_as_authorizable
  acts_as_audited :except => [:created_by, :updated_by ],
:user_class_name => 'AuthenticatedSystem', :user_method =>
'current_user'
  acts_as_ferret :fields => {:name => {:store => :yes},
                             :description => {:store => :yes},
                             :project_notes => {:store => :yes}}

  has_many :notes, :as => :notable
  .....

  def project_notes
    @index = Array.new
    for note in self.notes
      @index << note.details
    end
    @index.join(" ")
  end

  ..........

class Note < ActiveRecord::Base
  acts_as_authorizable
  acts_as_audited :except => [:created_by, :updated_by ],
:user_class_name => 'AuthenticatedSystem', :user_method =>
'current_user'
  acts_as_ferret :fields => {:details => {:store => :yes},
                             :notable_id => {},
                             :notable_type => {}}

  belongs_to :notable, :polymorphic => true

  ..........


But when i searched for a project with the note 'test':

  @results = Project.find_by_contents('test')

it returns 0 results. I checked in the logs and it created the index:

Processing NotesController#create (for 127.0.0.1 at 2006-12-11 13:53:53)
[POST]
.......
creating doc for class: Note, id: 17
Adding field notable_id with value '9' to index
Adding field details with value 'test project 9' to index
Adding field notable_type with value 'Project' to index
.......

I also added this to the NotesController:

def create
  @note = Note.new(params[:note])
  @note.disable_ferret(:index_when_finished) do
    @successful = @note.save
  end

  .....
end

This doesn't seem to work either, but after I have rebuild the index,
the note 'test' now appears on the results. Did I miss something here?


Any help is greatly appreciated.

Thanks much,
Jackie
