Bug 25043: Play with union

That will be hard to implement for our Koha::Objects

Speaking about the API use of this to circumvent the current DB issues, I think we can use an approach like this on the (very) few cases in which we have old* tables that might be requested to be included in the resultset.

So maybe is not a question of making it a core feature in Koha, but just using in the controllers to compose the result to be sent on the request response.

But I am afraid we won't be able to use object.search

All the pieces used in objects.search can be used, manually, on the controller method, so that's not a problem.

Still valid?
