Hello All,
I have a new requirement within my text search implementation to perform
stemming. I have done some research and implemented snowball, but however
the customers found it too aggressive and eventually I got them to agree to
compromise on k-stem algorithm.
Currently my existing code is on Lucene 2.9, which I would like to push to
the latest Lucene 4.3. So finally I have decided to build a custom analyzer
that implements kstem filter.
/ public class KStemAnalyzer extends Analyzer {
@Override
public final TokenStream tokenStream(String fieldName, Reader
reader) {
TokenStream result = new StandardTokenizer(Version.LUCENE_43,
reader);
result = new StandardFilter(Version.LUCENE_43, result);
result = new LowerCaseFilter(Version.LUCENE_43, result);
result = new StopFilter(Version.LUCENE_43, result,
StandardAnalyzer.STOP_WORDS_SET);
return new KStemFilter(result);
}
@Override
protected TokenStreamComponents createComponents(String string,
Reader reader) {
throw new UnsupportedOperationException("Not supported yet.");
}
}/
However I get an error /'tokenStream(String,Reader) in KStemAnalyzer cannot
override tokenStream(String,Reader) in Analyzer overridden method is
final'/. I was looking to find some documentation or example
implementations, but all I could find is the api that is not very
descriptive.
Any hint on how to initialize this would be highly appreciated.
Thanks.
