  Use filter tokens. 
  The logic of n-grams is that it adds underscores, so if you have 1 underscore you know it's a bigram, 2 is a trigram and so on. 
  So a regex as below would filter out bigrams, but you can extend to add additional grams. 
  
  ^[^_]+_[^_]+$
  
  Read as : start at beginning of word, take everything except an underscore, an underscore, and again everything except an underscore until the end of the word. So whatever matches must be a bigram.
