That is not an entirely bad idea depending on the web server's config.

I've not noticed any major ill effects of stemming on my system. It
generally works quite well. I added a minimum word length to my
stemmer.c, per Bill Moseley's suggestion I believe. That seems to
have clipped a number of false or inaccurate results lists. Short
words don't stem well and often look like something that should be
stripped. So you might end up with a 0 character word after stemming.

I would call it anything but slow. Total running time for my entire
script including forking SWISH is rarely more than a few hundred
milliseconds. It is almost instantaneous.

I added a bit of code to the output parser in my search script that
looks for "Stemming Applied: 1" and prints a note indicating that
stemming is active on that particular index. I did the same for my
Soundex module, as well. That way a search of multiple indices will
automatically indicate which options are active.

It could potentially do that. I'd be just as concerned with it not
matching words which it should. It is a trade-off, it will make a few
mistakes. You just don't want it to match or miss too many words
