See attached screenshot.

In this scenario, I searched for the "Home" page. Two existed, one in the test space (created by the UATs) and another in a space I had created, with space key 33.

The RPC result returned 1 home page - from Space 33.

The homepage in the test space had had its view restricted to confluence-admin.s but it was later reset to full publicity. This had no result on the search.
