A stack trace really would help a lot to identify what''s the problem.

I alse got this exception when i use the highlight function following 
the Acts_As_Ferret Tutorial on 
http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial

def find_storage_by_contents(query, options = {})
  index = self.ferret_index # Get the index that acts_as_ferret created 
for us
  results = []

  # search_each is the core search function from Ferret, which 
Acts_as_ferret hides
  total_hits = index.search_each(query, options) do |doc, score|
    result = {}

    # Store each field in a hash which we can reference in our views
    result[:name] = index.highlight(query, doc,
                    :field => :name,
                    :pre_tag => "<strong>",
                    :post_tag => "</strong>",
                    :num_excerpts => 1)
    result[:author_name] = index.highlight(query, doc,
                    :field => :author_name,
                    :pre_tag => "<strong>",
                    :post_tag => "</strong>",
                    :num_excerpts => 1)
    result[:score] = score   # We can even put the score in the hash, 
nice!

    results.push result
  end
  return block_given? ? total_hits : [total_hits, results]
end

With the introduction of the DRb server things have become a bit more
complicated here. You can access the ferret index instance when running
locally (no DRb) with Model.aaf_index.ferret_index, however this is not
intended to work with a remote ferret server.

The good news is that aaf has it''s own highlight method that you can
call on every record that has been returned as a search result from aaf:

highlight_strings = record.highlight(query, options...)

Please see the api docs for a list of options.

I found the answer; I had to use aaf_index.ferret_index instead of 
ferret_index

thanks every one
