Edge_ngram anchoring to the back

[dadoonet (David Pilato)]

You can use a combination of:

• https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-reverse-tokenfilter.html
• https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-edgengram-tokenfilter.html

[ "reverse", "edge", "reverse" ] so it will produce:

• [ kciuQ ]
• [ kc, kci, kciu, kciuQ ]
• [ ck, ick, uick, Quick ]

Thanks to @jpountz for the solution.
