There are some well-known filter aliases to match objects by certain
properties:
* $Object:ROOT \
With the `value` set to `true` checks if an object is a top object in a
split hierarchy. With other values returns non-root objects.
* $Object:LEAF \
With the `value` set to `true` checks if an object is a leaf in a split
hierarchy. With other values returns non-leaf objects.
* $Object:CHILDFREE \
With the `value` set to `true` checks if an object has empty
children list in `Split` header. With other values returns
non-childfree objects.
Returns only `REGULAR` type objects that are not split or are the top
level root objects in a split hierarchy. This includes objects not
present physically, like large objects split into smaller objects
without separate top-level root object. Other type objects like
StorageGroups and Tombstones will not be shown. This filter may be
useful for listing objects like `ls` command of some virtual file
system. This filter is activated if the `key` exists, disregarding the
value and matcher type.
