How to use the Porter Stemmber class in Lucene 3.6.2?
Here is what I have: 

```
import org.apache.lucene.analysis.PorterStemmer;
...
PorterStemmer stemmer = new PorterStemmer();
term = stemmer.stem(term);

```

I am being told: PorterStemmer is not public in org.apache.lucene.analysis; cannot be accessed from outside package.

Edit: I also read extensively about using Snowball, but it isn't encouraged. What is the right way to stem using Lucene in Java??
