This call is translated into the following request:

  GET /ovirt-engine/api/clusters?search=datacenter%3DPROD

And as you discovered this means "all clusters from all data centers
whose name contains PROD". This is by design, it isn't a bug.

If you only want the clusters of the "PROD" data center then you should
instead do something like this:

  prod_datacenter = api.datacenters.get(name="PROD")
  prod_clusters = prod_datacenter.clusters.list()

This is what ovirt-shell does when you run "list clusters
--datacenter-identifier PROD".
