Lucene Stemmer packages download

Question

I want to use these two classes from lucene -

 import org.apache.lucene.analysis.snowball.*;
 import org.apache.lucene.analysis.PorterStemmer;

But I am not finding these two classes in the lucene 3.5 that I downloaded. Can you tell me from where can I download the jar file having these two classes.

PS - I tried searching for lucene 3.0.1 jar but could not find it.

Thank You.

Answer 1

Strange, Porter Stemmer should be in the main JAR. However, the snowball analyzers are in the Lucene analyzers jar.
