I'm not a linguist, i'm just a programmer. SBL definitions look very uncommon
for me, i will try to find out where to put exceptions. May be you can
help me, how to add just one exception: stem Kiev => Kiev.

Or if it hard, as workaround I make my stemmer subclass which looks for exceptions
and use it, or if word is not listed in exceptions call Snowball.

No, this was first and only one problem (at least for now).
I'm writting search engine, which index all word in text.
And i noticed when i search "Kieva" (Kiev's or 'of Kiev' in english),
my search engine does not find text containing word "Kiev".

When i started to search where is the error i've found that stemmer,
stems 'Kiev' as 'Ki', and stem('Kiev') != stem('Kieva'), 
('Ki' != 'Kiev')

Thank you

PS. I'm sorry for my english.
