Hi Pierre,
I did the same thing some time ago. Here are the
highlights :
1- Create a FrenchStemFilter class that extends
TokenFilter
import net.sf.snowball.ext.frenchStemmer;
/**
* Constructor for SnowballFrenchStemFilter.
*/
public FrenchStemFilter(TokenStream in)
{
stemmer = new frenchStemmer();
input = in;
}
public final Token next() throws IOException
{
Token token = input.next();
if (token == null)
return null;
else
{
String s = stemmer.stem(token.termText());
// If not stemmed, dont waste the time creating a
new token
if (!s.equals(token.termText()))
return new Token(s, token.startOffset(),
token.endOffset(), token.type());
}
return token;
}
2- Finally create a FrenchAnalyzer that returns a
TokenStream whose tokens are filtered by the previous
stemmer.
Hope that it can help you.
