If you're using jQuery you could do something like this to have the form auto-post on keyup events, or simplify it to trigger manually:

  $(function() {    
    $("#live_search input").keyup(function() {
        q = $('#search_text').val();
      $.ajax({
          beforeSend      : function(request) { request.setRequestHeader("Accept", "text/javascript"); },
                           // Included so Rails responds via "format.js"
          data          : 'query=' + q,
          success       : function(data, textStatus, XMLHttpRequest) {
                                // alert(textStatus);
                                $("#live_search #results").html(data);
                                },
          error         : function(XMLHttpRequest, textStatus, errorThrown) {
                                // alert(errorThrown);
                                $('#annotation_dialog').html(XMLHttpRequest.responseText);
                                },
          type            : 'POST',
          url                 : '/search/live'
      });
      return false;
    });
});
