Our email crossed in the ether - I posted "swish-e -D" and "grep" results
last night. Indeed, "rock" is not found when searching for "rockies", but
"rocky" is found when searching for "rockies" via stemming to "rocki".
One could argue that "rocky" is a derivative of "rock", and as such
"rocky" should stem to "rock" instead of "rocki", but I'm no expert
on how stemming was designed... and with English you'll never get
all the special cases right.

The form is set up to strip all that stuff, which is why I turned
stemming on in the first place (poor man's wild card?).
What's the general opinion of people who've been using swish for a long
time? Does stemming pay off? Is it too slow, does it return false hits
that confuse the lo-tech users? (My site has no expectations yet, as
this is the first search option we've made available and it's not even
