: And if I search for "refrigerador", I'll have all results for "refrigerador", : for "geladeira", and all results for the flexed words for what i've typed : (refrigerador, refrigerado, refrigeração, etc). But I won't find the results : for the flexed words of the synonym that i've defined (geladeira), for example : "gelado, gelo, etc".
I'm not sure what "flexed" means ... it looks like you are refering to other words with a common stem. if you use the SynonymFilter before you use your stemming filter, it should work fine. -Hoss
