How to write a custom stemmer for Apache Solr

[nitishgarg <ni...@gmail.com>]

 have figured out that the stemmers already built in Apache Solr are
contained in org.apache.lucene.analysis.nl.* (for Dutch) but I can't find
this package in my Lucene folder. 
Also I need to write a stemmer for marathi language, any help how should I
proceed?

In trunk, it'll be somewhere like:
\modules\analysis\common\src\java\org\apache\lucene\analysis\nl

but you haven't said what version you're using. Modules is a relatively
new division of code, so it may be in contrib if you're on an earlier
version.

I have no clue about the details of what a Marathi stemmer should #do#, but
it's just another filter from the Solr perspective, so model it on
any of the filters. Subclass from TokenFilter. Probably LowerCaseFilter
is a good model. Drop the resulting jar in a place Solr can find it and you
should be good.

Best

Hi

Have you tried Lucene-HunSpell with Marathi dictionary ?
