User-friendly Search results page

[X.O.]

I would like to modify the search results page when it says 'There is no product that matches the search criteria.' and include the Advanced Search fields. In other words, when search result is empty Advanced Search is offered on the same page.
I suppose I should edit \includes\modules\product_listing.php file but I am not familiar with PHP.
Please advise how to achieve this so the Search Engine will be more user-friendly.
Thanks.

/includes/modules/pages/advanced_search_result/header_php.php
near the bottom of the file, you have a section of code like the following.
Add the highlighted lines to get the effect you mentioned:

$breadcrumb->add(NAVBAR_TITLE_1, zen_href_link(FILENAME_ADVANCED_SEARCH));
$breadcrumb->add(NAVBAR_TITLE_2);

$result = new splitPageResults($listing_sql, MAX_DISPLAY_PRODUCTS_LISTING, 'p.products_id', 'page');
if ($result->number_of_rows == 0) {
  $messageStack->add_session('search', TEXT_NO_PRODUCTS, 'caution');
  zen_redirect(zen_href_link(FILENAME_ADVANCED_SEARCH, zen_get_all_get_params('action')));
}

// This should be last line of the script:
$zco_notifier->notify('NOTIFY_HEADER_END_ADVANCED_SEARCH_RESULTS', $keywords);

Perfect! Thanks Dr.Byte!
