[Snowball-discuss] Porter stemming not dealing well with -gist -gists

[Martin Porter]

Hi Marc,

The "Porter stemmer" is now frozen in time, but this could be a
something to add to the snowball "English stemmer". It's connected to
the fact that -ist is not, in general, removed. -ologist -> olog
could, however, be added.

I've put your suggestion on the snowball-discuss list,

Thanks, Martin
