Moving to Search 6.

Most of the infrastructure necessary to integrate an even source/datastore other than Hibernate ORM is already available in Search 6. You simply need to write a custom mapper derived from the POJO mapper.

However, it seems this ticket is supposed to benefit to Hibernate Search users, not integrators.
If so, we need to make things simpler in Search 6, or at least add documentation about how to write a (simple) mapper.
