Hi all,  
Is there anyway to keep the words that shorter than min length of ngram ?  
For example:  
the data is "abc x" ==\> ngram(2,4) will generates: ab, bc, abc. It remove  
"x" since "x" has length=1. I want to keep "x" because it still a keyword.  
What filters I need to use in order to keep it? I'm using ES 0.90 ?  
I think ngram should have an option to keep shorter words like this case.

Thanks,  
Duc
