Only preload ancestors for search results in the specified parent

When filtering we want all to preload all the ancestors upto the specified
parent group.

- root
  - subgroup
    - nested-group
      - project

So when searching 'project', on the 'subgroup' page we want to preload
'nested-group' but not 'subgroup' or 'root'
