Robert Muir commented on LUCENE-5208:
-------------------------------------
Hi, instead of modifying SnowballFilter directly, I think sometign like this
should instead just be a LengthKeywordMarkerFilter or something.
if (length < X) { keywordAtt.setKeyword(true); }
this will work with all stemmers, not just snowball.
> SnowballFilter to support minTokenLength

> In some cases you don't want the stemmer to consider short tokens. Instead of
> modifying the snowball code, testing it, compiling it to Java code and the
> whole hassle, with this patch you can set a minTokenLength.
