Max edit distance and suggestion based on word frequency

I need a spell checker with the following specification:

  • Very scalable.
  • To be able to set a maximum edit distance for the suggested words.
  • To get suggestion based on provided words frequencies (most common word first).

I took a look at Hunspell:
I found the parameter MAXDIFF in the man but doesn't seem to work as expected. Maybe I'm using it the wrong way

file t.aff: 

MAXDIFF 1

file dico.dic: 

5  
rouge  
vert  
bleu  
bleue  
orange

- 

NHunspell.Hunspell h = new NHunspell.Hunspell("t.aff", "dico.dic");
List<string> s = h.Suggest("bleuue");

returns the same thing t.aff being empty or not:

bleue
bleu
