thanks, scain! tachyon, that is quite a lot of code to digest! but thanks also. i don't understand how it works, because i don't see $link_results anywhere, or maybe i could substitute one of the variables you wrote to $link_results? should it be $filter? here some more codes that might interest you:

a chunk from search.cgi:

# If we want to bold the search terms...
    if ($search_bold) {
        foreach $term (@search_terms) {
# This reg expression will do the trick, and doesn't bold things insid
+e <> tags such as 
# URL's.
            $link_results     =~ s,(<[^>]+>)|(\Q$term\E),defined($1) ?
+ $1 : "<b>$2</b>",gie;
        }
    }

$searchbold is defined in a file called links.cfg. if it is set to 1, bolding is activated, otherwise if equal to 0. Further down in search.cgi, it says:

# Print out the HTML results.                  
    &site_html_search_results;
}

That sub could be found in another file called site_html_templates:


sub site_html_search_results {
# ---------------------------------------------
# This routine displays the search results.
# 
    my $term    = &urlencode ($in{'query'});
    &html_print_headers;
    print &load_template ('search_results.html', {
                   lookup => $lookup_results,
                   antsym => $lookup_antsym,
                   term => $term,
                   ignored_word => $ignored_word,
                   link_results => $link_results,
                   category_results => $category_results,
                   prev => $prev,
                   next => $next,
                   cat_hits => $cat_hits,
                   cat => $cat_clean,
                   link_hits => $link_hits,
          title_linked => $title_linked,
          displaying => $displaying,
          results_page => $results_page,
          csearch_results => $csearch_results, 
                   %in,
                   %globals
                   });
}

So, from what you suggested, I'm guessing that I may have to revise three different files. but i've no idea how to go about doing that! Sorry that i wasn't able to post codes immediately. I hope i didn't waste your effort. thanks, i really really appreciate your help!
