Hi, In order for this integration to work you need to start by creating a  hibernate search directory provider for Cassandra, assuming you are already able  to store a Lucene Directory in Cassandra columns, otherwise you'd need to create it as well.

There are some Lucene-Cassandra integrations around, for example [1], and for an example of creating a HIbernate Search Directory Provider for a Nosql store, you could refer to [2] or the implementation of the infinispan directory provider [3]

[3] https://github.com/hibernate/hibernate-search/tree/master/infinispan

With the new directory provider, it should be easily pluggable in Infinispan using the property "default.directory_provider"  equals to the implementation class
