The script needs to be updated as it no longer searches websites.
I can get the script to update search.tmp for xdccfinder by changing occurences of
xdccb-addoption search /results.php?search= $+ %search
to
xdccb-addoption search /results.php?kw= $+ %search
but the problem lies with parsexdccfinder as the website now returns slightly different results.
