Oleg,

The Porter stemming stems herring and herrings to her, which is a bit
unfortunate. A quick fix is to put 'herring/herrings' in the exception list
in the english (porter2) stemmer, but I'll look at this case over the next
few days and see if I can come up with something a bit better.

Interesting that no one has reported this before.

Martin

Unfrtunately, we wrote tsearch module before the Snowball project has started,
so we used one implementation we found in the net (www.muscat.com) and
there is no exception list. OpenFTS uses snowball stemming, so we'd like
to have a fix. I think we have enough arguments to use snowball stemmers
in tsearch also.
