Rails - Sep 2007 - acts_as_ferret MultiIndex

Hello,

I am working with Ferret and acts_as_ferret.

I have 9 different models that I am using for my search capability.
acts_as_ferret is working beautifully when I do searches on a specific
model.

The problems come when I try to do a `search all` function.

==================
I can easily get a proper collection using the following method:

def search_all
	@results = []

	[Announcement, Event, Group, Job, Need, Offering, Organization,
Pedia, User].each do |model|
		finds = model.find_by_contents(@query)
		finds.each {|find| @results << find } unless finds.blank?
	end

	@results = @results.sort_by { |result| result.ferret_rank }
	@results.reverse!
  @total = @results.length
end

==================
The problems come in that I have no way to implement pagination, or
specify any further details.

I have been reading about Ferret::Index::MultiIndex does anyone know
how to use it?  It would be of great help as it does what I wish.

--OR--

Does anyone have any suggestions for a better way to implement an
effective search across many different indexes?

Thanks!!

i think it would be easier to modify their versions to match yours. :)

good luck

in one of my apps I did this:

<pre>
  def search
    if params[:search_article] && params[:search_article][:q] !=
""
      limit = 20
      order_by = "title ASC"
      @articles = Article.full_text_search(params[:search_article]
[:q], limit, order_by)
      order_by = "first_name ASC, last_name ASC"
      @users = User.full_text_search(params[:search_article][:q],
limit, order_by)
      order_by = "first_name ASC, last_name ASC"
      @birthdays = Birthday.full_text_search(params[:search_article]
[:q], limit, order_by)
    else
      @birthdays = []
      @users = []
      @articles = []
      flash[:notice] = ''No fue encrontrado nada con esta
criteria.''
    end
  end
</pre>

model code:

<pre>
  def self.full_text_search(q, limit, order_by)
     return nil if q.nil? or q==""
     results = self.find_by_contents(q,
      :order => order_by,
      :limit => limit
     )
     return results
  end
</pre>
