Stemming

["Kevin L. Cobb" <ke...@emergint.com>]

I want to understand how Lucene uses stemming but can't find any
documentation on the Lucene site. I'll continue to google but hope that
this list can help narrow my search. I have several questions on the
subject currently but hesitate to list them here since finding a good
document on the subject may answer most of them. 

 

Thanks in advance for any pointers,

 

Kevin

Hi Kevin,

Stemming is an optional operation and is done in the analysis step. 
Lucene comes with a Porter stemmer and a Filter that you can use in an
Analyzer:

./src/java/org/apache/lucene/analysis/PorterStemFilter.java
./src/java/org/apache/lucene/analysis/PorterStemmer.java

You can find more about it here:
http://www.lucenebook.com/search?query=stemming
You can also see mentions of SnowballAnalyzer in those search results,
and you can find an adapter for SnowballAnalyzers in Lucene Sandbox.
