Cool, I was just trying to think of an example!

You could usefully use a stemmer like this for IR without major changes
to the IR system I think.  Xapian (www.xapian.org) would accommodate it
anyway.

If multiple forms are all indexed, and OR-ed when processing queries,
then a search for "route" would match "routing", but not "rout".  A
search for "routed" would matching "rout", "route", and "routing".  And
so on...
