There is only maxShingleSize right now. The other configurable attribute is
outputUnigrams which controls whether or not unigrams may be added to the
index.

If you want to add support for minimum size, I think you can make the
changes in ShingleFilter.fillShingleBuffer(). Create an issue in jira and
someone who knows more about shingles can help out.
