    Description

      Spinoff from http://lucene.markmail.org/message/uq4xdjk26yduvnpa

      I noticed that if I set outputUnigrams to false it gives me the same output for
      maxShingleSize=2 and maxShingleSize=3.

      please divide divide this this sentence

      when i set maxShingleSize to 4 output is:

      please divide please divide this sentence divide this this sentence

      I was expecting the output as follows with maxShingleSize=3 and
      outputUnigrams=false :

      please divide this divide this sentence
