Highlight search results

[altenter]

Hello,
I am trying to highlight the search results from the search box.
I followed this tip/trick, made a few fixes to the _GET issue, replacing it with HTTP_GET_VARS.
This is the product_listing.php change for PRODUCT_LIST_NAME:

case 'PRODUCT_LIST_NAME':
$lc_align = '';
if (isset($HTTP_GET_VARS['manufacturers_id'])) {
$lc_text = '<a href="' . tep_href_link(FILENAME_PRODUCT_INFO, 'manufacturers_id=' . $HTTP_GET_VARS['manufacturers_id'] . '&products_id=' . $listing[$x]['products_id'] . $parm_add) . '">' . highlight_viewable_text($listing[$x]['products_name'], $HTTP_GET_VARS['keywords'], 'searchTag') . '</a>';
} else {
$lc_text = '&nbsp;<a href="' . tep_href_link(FILENAME_PRODUCT_INFO, ($cPath ? 'cPath=' . $cPath . '&' : '') . 'products_id=' . $listing[$x]['products_id']) . '">' . $listing[$x]['products_name'] . '</a>&nbsp;';
}
break;

This is the product_info.tpl.php part:

if ($display_search_results) {
// highlight
$products_name = highlight_viewable_text($product_info['products_name'], $HTTP_GET_VARS['keywords'], 'searchTag');
} else {
// normal
$products_name = $product_info['products_name'];
}

and:

if ($display_search_results) $product_info['products_description'] = highlight_viewable_text($product_info['products_description'], $HTTP_GET_VARS['keywords'], 'searchTag');

This is the url i am recieving when searching for 'radio' from the search box:

http://www.myshop.com/advanced_searc...dc1223299&hl=1

Any ideas what other differences are affected using max rc3, or another way to make this work?
Thanks

forgot to mention, i also added tep_hide_session_id() . tep_draw_hidden_field('hl',1) to the search box.

Can anyone point me to the right direction to achieve the search word highlighted in the results?
Only results from the search box are needed to be highlighted.
Thanks.
