Summary: a single deny filter of form '*term=*' does not function.

I attempt creating a mirror:
HTTrack version 3.43-9+libhtsjava.so.2
httrack <http://www.etymonline.com/>

With following nice .httrackrc:
#######
sockets 1
keep-alive
max-rate=43210
stay-on-same-address
can-go-down
path="/usr/local/share/httrack"
deny *term=*
#######

HTTrack still retrieves things that I think should match the deny filter,
like:
www.etymonline.com/index.php?term=-ance
Why?
