I wrote a small bit of Perl code to transform url-references attributes
in selectable hyperlinks.  If you want to have url-references as
hyperlinks, modify your BrokerQuery.cf this way:

<MatchedLineSub>
s/^Matched line:\s*//;
# Make URL-references selectable
/^url-references\#\s*(.*)/;
$url_references = $1;
if ($url_references =~ m#(http|ftp|gopher)://([A-Za-z\-\.0-9]+)(:[0-9]+|)#) {
        s/^url-references\#\s*.*/url-references\# <A HREF=\"$url_references\">$url_references<\/A>/i;
}
# indent four spaces
s/^.*/    $&/;
</MatchedLineSub>

You can check the result on our broker
<http://www.pasteur.fr/search/Pasteur-en.html>. Try "Ebola" (the famous
virus) for instance. Do not forget to ask for "Display matched lines".
