Hi Chris,
your suggestion makes sense but I'm afraid we won't have time to work on this ourselves. If you want to give it a shot I'd be happy to give you some guidance?

Some things to keep in mind:

• we're working on Hibernate Search 6, the specifics of how to integrate such a thing are not defined yet.
• does Hazelcast have a way to store a Lucene index? (hopefully reliable and well performing?)

Depending on your timeline, you might want to do this for Search 5 which uses Lucene 5.5.x . If you would rather wait for Hibernate Search 6.x then we're aiming at Apache Lucene 7.x.
