If you want the widget to trigger the Ajax call only if 4 chars or
more were entered have a look at the :min_chars option:

rails/auto_complete/blob/master/lib/auto_complete_macros_helper.rb

module AutoCompleteMacrosHelper      
  # Adds AJAX autocomplete functionality to the text input field with the 
  # DOM ID specified by +field_id+.
  #
  # This function expects that the called action returns an HTML <ul> list,
  # or nothing if no entries should be displayed for autocompletion.
  #
  # You'll probably want to turn the browser's built-in autocompletion off,
  # so be sure to include an <tt>autocomplete="off"</tt> attribute with your text
  # input field.
  #
  # The autocompleter object is assigned to a Javascript variable named <tt>field_id</tt>_auto_completer.
  # This object is useful if you for example want to trigger the auto-complete suggestions through
  # other means than user input (for that specific case, call the <tt>activate</tt> method on that object). 
  # 
  # Required +options+ are:
  # <tt>:url</tt>::                  URL to call for autocompletion results
  #                                  in url_for format.
  # 
  # Addtional +options+ are:
