Xwiki + Tagging: List Specifically Tagged Pages Only From Specific Spaces Hierarchy

I’m just playing around with Tags in Xwiki.

I can list all pages having a certain tag just fine, but so far I could not find a way to display pages with a specific tag only from a specific pages hierarchy.

In my Wiki instance I used multiple top-level spaces hierarchies for stuff covering different topics, and I now want to generate overviews over e.g. Checklists or HowTos individually for each hierarchy.

Is there any way to easily achieve this?
