# visible to a specified user.

# of the `parent_group`. All ancestors for a search result are loaded
#
# Arguments:
# current_user: The user for which the children should be visible
# parent_group: The group to find children of
# params:
# Supports all params that the `ProjectsFinder` and `GroupProjectsFinder`
# support.
#
# filter: string - is aliased to `search` for consistency with the frontend
# archived: string - `only` or `true`.
# `non_archived` is passed to the `ProjectFinder`s if none
# was given.
