You don't enable it. If the index was *created* with stemming then
that's what is used in the API.
$fuzzy_word = $swish->Fuzzify( $indexname, $word );
You have to specify the index so it knows which stemming algorithm to uses.
$fuzzy_word = $result->fuzzy_word( $word )
That doesn't need to know the index because it's a method on the
$result object and a result is tied to a given index. That is, it
implicitly knows what index to use.
(Peter, those methods have changed, right? Seems in the test.t file
they return a Wordlist instead. Sounds familiar. Is that because
Snowball can sometimes return two stems?)

Yes, queries are stemmed automatically, if that's the question.

See the SWISH::API t/test.t file

No, you should not get that. That's not how the stemmer works. The
stemmer gives you the stem, not all variations of the word.

If you want that you will have to use other means. Maybe feed a
dictionary into the stemmer then index all words by their stem.
