Accent insensitive terms

(from github.com/EyadA)
Hi there,

Is it possible to return results with Ascii folding? Example, GSA allows you to search for hopital and hôpital or securitaire and sécuritaire and you would get the same results.

ElasticSearch has an asciifolding filter:https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-asciifolding-tokenfilter.html but I am unsure how I can apply it. Any suggestions?

You can edit app/WEB-INF/classes/fess_indices/fess/doc.json and then start reindexing on Upgrade page.
