Does anybody know how to use hibernate-search or infinispan-query to query inside a pre-existent index (loaded with LuceneCacheLoader inside Infinispan Directory)? In my use case I don't need and I don't want a relational DB. I just want to bring the index in the infinispan cluster and make it searchable and updatable through hibernate-search. How to achieve that? All hibernate-search use cases I googled in relate to indexing data (through POJO annotation) retrieved from a DB. Is hibernate-search suitable also in my use case?
