> 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

> The GeoHashFilteredDocIdSet is assuming the values are always in the cache

> Dictionary distanceLookupCache, double lat, double lng, int 
> docBase, double distance, Dictionary distances) 
> : base(innerSet , (docid) => /* was: public override Match */

>   String geoHash = geoHashValues[docid];
>   double[] coords = GeoHashUtils.Decode(geoHash);
>   double x = coords[0];
>   double y = coords[1];
>   double cachedDistance;
> distanceLookupCache.TryGetValue(geoHash, out cachedDistance);
>   double d;
>   if (cachedDistance > 0)
>   {
>   d = cachedDistance;
>   }
>   else
>   {
>   d = 
> DistanceUtils.GetInstance().GetDistanceMi(lat, lng, x, y);
>   distanceLookupCache[geoHash] = d;
