It does employ stemming, here is the AliasAnaylzer class. I will also create a sample
program as Daniel had suggested.
import java.io.Reader;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.LowerCaseFilter;
import org.apache.lucene.analysis.StopAnalyzer;
import org.apache.lucene.analysis.StopFilter;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.PorterStemFilter;
public class AliasAnalyzer extends Analyzer {
public AliasAnalyzer() {
}//end constructor
public TokenStream tokenStream(String fieldName, Reader reader) {
TokenStream result = new AliasFilter(
new StopFilter(
new LowerCaseFilter(
new AlphanumericTokenizer(reader)),
StopAnalyzer.ENGLISH_STOP_WORDS));
result = new PorterStemFilter(result);
return result;
}//end tokenStream
}//end AliasAnalyzer

Subject: Re: Failure of wildcard search in the middle of a term
Does your analyzer employ stemming? Maybe the ending gets ripped off and the
word is indexed as 'calgarian' or even 'calgar'.
Did you write the Analyzer yourself? I can't find it in any package to see
whether it does stem tokens...
