Dear All,
I'd like to integrate a new Snowball stemmer [1] to Lucene for my
experiments, but I can see some incompatibilities between original Snowball
stemmers (produced via Snowball compiler) and actual Lucene's Snowball
stemmers [2].
Especially:
* different constructor of Among class: new Among("ce", -1, 1) vs. new Among
("ce", -1, -1, "", methodObject)
* in the find_among_b() method only two params are accepted
What is the procedure for producing Lucene-compatible stemmers from SBL
file? Is there any automation or should I modify that original compiled file
manually?
Thanks,
Jan

[1] It is actually a Czech stemmer, see
https://issues.apache.org/jira/browse/LUCENE-4042, eventhough the original
author has stated in LUCENE-3883: I wouldn't recommend the aggressive mode,
and I regret that I left it uncommented. If you really think an alternative
would be welcome, it would be quite easy to get the best of both (in fact, I
spent roughly half the time on that trying to beat Snowball into
overstemming to match the original).
[2] Lucene stemmers can be found here:
