No swish has not idea.  The stemming is done at indexing time, not
search time.

The example swish.cgi script can use the PhraseHighlight Perl package
to highlight text on stemmed indexes - it does that by stemming the
text to look for matches.  That can be quite slow.

SWISH::API (and the C library) provide ways to use the same stemming
code used while indexing.
