Isis is most often used with its JDO integration, a fairly conventional ORM. Searching for existing domain objects therefore requires a query to be defined. But sometimes users want to just search for any object (like searching the web). This ticket is to integrate Isis so that its domain objects can be indexed by Lucene and thus provide a generic search capability.

Then one would also provide some sort of repository to query the Lucene datastore:
There is also an attachment to this ticket, based on an earlier spike by Maurizio. Note that that was done before the subscribers were available.
