Lucene Porter Stemmer not public

Question

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          


        

Answer 1

In Lucene later version, PorterStemmer no longer public. So

 class MyAnalyzer extends Analyzer {
   public final TokenStream tokenStream(String fieldName, Reader reader) {
    return new PorterStemFilter(new LowerCaseTokenizer(reader));
   }
   }

Or you can use SnowballAnalyzer Stemmer.link (SnowballAnalyzer is deprecated)

import org.tartarus.snowball.ext.PorterStemmer;
.
.
public static  String applyPorterStemmer(String input) throws IOException {

        PorterStemmer stemmer = new PorterStemmer();
        stemmer.setCurrent(input);
        stemmer.stem();
        return stemmer.getCurrent();
    }
