​Yes! It would be great to have Infinispan's extensions set it up, as we
don't ship any such component. So this is left as an "exercise to the user"
for now.. Infinispan could do better ;)

There are pointers in the release blog, I linked to it in my previous email:
​ - http://in.relation.to/2017/06/13/hibernate-search-5-8-0-Beta3/

Essentially our testsuite contains fully working examples.

Thanks,
Sanne
