Ancestor Filters for Live Search Macro

It would be incredibly useful to add the ancestor filter to the Live Search macro.

Due to the nature of the content, our user base, and level of content sharing we have in a space, we have roughly 30 parent pages that contain over 5,000 children / grandchildren pages. The content has been built out over a period of years and it has grown to a point where it requires a comprehensive audit and re-architecture. We know that our users struggle to navigate the page tree and to execute searches using the filters.

We believe that one option that could greatly benefit our users would be to remove the page tree from the sidebar and to include multiple Live Search macros (containing the ancestor filters) that point directly at the relevant hierarchy.
