Bakcport fix #2553 add hypen to Fess 13.10.x?

Is it possible to have fix #2553 add hypen backported to version 13.10.x?

We are kinda stuck with custom analyzer which is currently available only to Elasticsearch version 7.10.0.

We have no plan to release 13.10.x. (but I think Fess 13.12 works with Elasticsearch 7.10…)

Thank you for quick reply.
