To use $pod_usequery=0 without getting the searchstring for the amazon searches,
change the lines in pod.cgi that prints this and before that, remove the rubbish from
the searchstring. See it working at www.berka.com

# remove rubbish
@split_top = split(/\&/, $pod_topic);
$pod_topic_top = $split_top[0];

# in call to maxcomm, use $pod_topic_top (don't put this line in script!)
<a href="$pod_maxcomm?keyword=$pod_topic_top&whichamazon=$pod_whichamazon&tag=$pod_amazon_ID">
<b>$pod_topic_top</b></a></b> at $pod_bookstorename.
