NGram exact match varying results

[dodgy99]

I am using this library in an Apache Spark application (using scala).

I have been seeing variable results using the NGram algorithm where exact matches result is either "0.0" or "1.0". Below are some examples.

`QGram dig = new QGram(2);

dig.distance("S","S")
//result = 1.0

dig.distance("Kirk","Kirk")
//result = 0.0

dig.distance("07426796542","07426796542")
//result = 0.0`

Should all these examples not result in a score of 1.0 as they are exactly the same?

Hi, Thank you! This happens because the strings "S" are two short (less then 2 characters). I will correct this and publish a new release...

Fixed in release 0.21
