Maybe you could sort the letters of each word into alphabetic order and use a hash to make the link between sorted words and real words. Then also sort your input letters. I am not sure right now on how to go from there (possibl building a HoH), but I think that "normalizing" the words this way should enable you to do much faster lookup.
