Autocomplete and bold highlight
I've gone from the Jorn autocomplete plugin to the jQuery UI autocomplete plugin. Not sure why, because I liked Jorn's plugin but it feels better to use jQuery UI. Here's my hack to make the searched for work highlit.
  
   -   $('#id_q').autocomplete({
    source: function(request, response) {
      $.ajax({
        url: AUTOCOMPLETE_URL,
        dataType: 'json',
        data: { q: request.term },
        success: function(data) {
          response($.map(data, function(item) {
            return {label: __highlight(item.title, request.term) + " (" + item.type + ")",
                    value: item.title};
          }));
        }
      });
    },
    minLength: 2)
  .data( "autocomplete" )._renderItem = function( ul, item ) {
                  // only change here was to replace .text() with .html()
                  return $( "<li></li>" )
                        .data( "item.autocomplete", item )
                        .append( $( "<a></a>" ).html(item.label) )
                        .appendTo( ul );
                };
 
   
 
  
The highlight function might need some work but it works.
    
     - function __highlight(s, t) {
  var matcher = new RegExp("("+$.ui.autocomplete.escapeRegex(t)+")", "ig" );
  return s.replace(matcher, "<strong>$1</strong>");
}
