Class EdgeNGramTokenFilter
Tokenizes the given token into n-grams of given size(s).
This TokenFilter create n-grams from the beginning edge or ending edge of a input token.
As of Lucene 4.4, this filter does not support BACK (you can use ReverseStringFilter up-front and afterward to get the same behavior), handles supplementary characters correctly and does not update offsets anymore.
