Review Comment:
We have `getTopChildren` in other facet demo examples. I think that should
be sufficient for now? However, it might be worth to make an example for
children with 0 count and call `getTopChildren` and `getAllChildren` in
parallel to demo the different results? I can add this example to
`TestSimpleFacetsExample` if you think it is useful. Thanks!
