Okay. The scriptindex documentation should make that a little more
obvious. I admit that my view isn't actually supported by the text,
but it's not discouraged either - something at the end of the
'unique' description, such as:

  The 'unique' action will not generate any terms; it is most useful in
  combination with the 'boolean' action (with the same PREFIX).

What I wasn't sure was what the queryparser would do with the term in
that case. I /thought/ it would just split it, wheras what I want it
to do is split to get the term, then strip the prefix off, stem the
rest, and put the prefix back on again.

At least, I think that's what I'd want :)
