Attached is the modified Snowball source code for plural-only English stemmer. You need to compile it to Java using instruction here: http://snowball.tartarus.org/runtime/use.html. Essentially, you need to:
1) Download (Snowball, algorithms, and libstemmer library)<http://snowball.tartarus.org/dist/snowball_code.tgz> and compile Snowball compiler it self using this command: gcc -O -o snowball compiler/*.c. 2) Compile the the attached file to Java: ./snowball stem_ISO_8859_1.sbl -java -o EnglishStemmer -name EnglishStemmer You can change EnglishStemmer to whatever you like, for example, PluralEnglishStemmer. After that, you need to modify the generated Java class so that it references the appropriate classes in net.sf.snowball.* package instead of the one from Snowball website. I think only 2 classes you need to import are Among and SnowballProgram. Once, you have the new stemmer ready, write something similar to EnglishPorterFilterFactory to use it within Solr. Hope this helps.
