Leading wildcard search handling

We need to allow leading wildcard searches on our Elasticsearch installation and I'm looking for the best way to handle them.

What for? Can you explain the use case for it?

Add a reversed field for all the fields we want the leading wildcard to work for and use an edge n-gram filter to run the query using the index.

Definitely, I'll go that way. Have a look at:

Edge_ngram anchoring to the back

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.
