Hi,
I'm currently working on a prototyp, where I have to add "Google" like Searching to our existing application. To keep the deployment simple, Elasticsearch is not a preferable option. But still there is a requirement for Multinode deployment.

So my setup is like that: HibernateSearch with Infinispan backend. Each node should have his local index, to keep the index alive, the plan is to save the index to a persistence database. This because there is also the requirement, to restart a single node server without loosing the index.
As the configuration for Infinispan is different on 8.xx and 9.xxx (Infinispan Persistence Example, I tried to use the newest version.
But excluding the depencendy in Maven for both ends didn't help.
