just specify your analyzer with the :analyzer option, i.e.

  acts_as_ferret :analyzer => GermanStemmingAnalyzer.new


Here''s what my GermanStemmingAnalyzer looks like:

class GermanStemmingAnalyzer < Ferret::Analysis::Analyzer
  include Ferret::Analysis
  def initialize(stop_words = FULL_GERMAN_STOP_WORDS)
    @stop_words = stop_words
  end
  def token_stream(field, str)
   
StemFilter.new(StopFilter.new(LowerCaseFilter.new(StandardTokenizer.new(str)),
@stop_words), ''de'')
  end
end
