> Italian stemmer does not work.
> Consider this code:
> var englishAnalyzer = new SnowballAnalyzer("English");
> var tk = englishAnalyzer.TokenStream("text", new StringReader("horses"));
> var ta = (TermAttribute)tk.GetAttribute(typeof(TermAttribute));
> tk.IncrementToken();
> Console.WriteLine("English stemmer: horses -> " + ta.Term());
>
> var italianAnalyzer = new SnowballAnalyzer("Italian");
> tk = italianAnalyzer.TokenStream("text", new StringReader("abbandonata"));
> ta = (TermAttribute)tk.GetAttribute(typeof(TermAttribute));
> tk.IncrementToken();
> Console.WriteLine("Italian stemmer: abbandonata -> " + ta.Term());
> It outputs:
> English stemmer: horses -> hors
> Italian stemmer: abbandonata -> abbandonata
> While Java Lucene 2.9.4 outputs:
> English stemmer: horses -> hors
> Italian stemmer: abbandonata -> abbandon
