I tried the pod logging and I noticed it logged not just searches, but also every click
in the directory (as a search for nothing). I don't know if this was the purpose of the
script, but it wasn't what I wanted.

Suggestion,

change the line:
if (defined($pod_logging)) { &pod_log_search($pod_cgi_search); }

to:
if ((defined($pod_logging)) and (defined($pod_cgi_search))) { &pod_log_search($pod_cgi_search); }

kindly
