Question regarding Stemmer
Hi
i want to get some answers to some of my questions.
Going by the Solr Wiki There are three approaches for Stemming
Porter or Reduction Algorithm
As far as i know there is "solr.EnglishPorterFilterFactory" and there is
"solr.SnowballPorterFilterFactory" Both uses the same stemming algorithm.
Hence i assume the only difference is that SnowBall allows you to specify a
language.
is my asssumption correct?
The other thing is that the wiki talks about "solr.PorterStemFilterFactory"
and that uses PorterStemming Algorithm but doesn't have any example
specifying how to declare a field type with that kind of stemmer.
Could any body give some snippet.
Expanssion Stemming By using SynonymFilterFactory

Kstem which is less aggressive stemmer
When i click the download the jar it doesn't work for the past two days.
Dont know exactlty when it will be working.
Thanks
darniz
