Agreed - this is noticeably absent in WinHTTrack, even with the F1
(context-sensitive) Help.  Once I became aware of this option:
  %[param] param variable in query string
I did a search and found detailed usage syntax here:
  <http://httrack.kauler.com/help/User-defined_structure>
[...]
%[param:before:after:empty:notfound] advanced variable extraction
  param : parameter name
  before : string to prepend if the parameter was found
  after : string to append if the parameter was found
  notfound : string replacement if the parameter could not be found
  empty : string replacement if the parameter was empty
all fields, except the first one (the parameter name), can be empty
[...]

LOL in fact, just about a day before you (Scarbrow) posted this, I posted a
case where using this feature was the only solution I could think of to help
with a certain mirror:

Very, VERY useful, indeed!
