If there are multiple pages on phriction with same title, it makes easier to find the page you need if parent pages are displayed.

For example imagine following structure: "Home > Project Name > Runbook", where [Project Name] is different for each Project and "Runbook" is page which every project has.
If I'd search what is in few runbooks, I'll get simple list:

**Runbook**
Phriction Wiki Document

**Runbook**
Phriction Wiki Document

**Runbook**
Phriction Wiki Document

Having parent page in results (in this case it is project name) would help me a lot to identify required page:

Project A > **Runbook**
Phriction Wiki Document

Project B > **Runbook**
Phriction Wiki Document

I remember we had this implemented before, but can not find task why it was removed.
