Is it a bug? Can't filter

Also I have several concerns about groups.
I'm working with groups now, and I have found, that they don't have identifiers.
Could you share idea around to don't have ids for groups?
I think you should use identifiers for every entity that you have. Or if you want to have name as a key, please provide instruments to have clean keys, now you just push name (Example: 'Beaver Lovers all over the World') as key... as a result it produces document with a key group:Beaver Lovers all over the World
If you like names as keys, I think, these changes should be made:
- introduce additional field, for example
displayName
, because name
is part of identification of the document
- use clean keys, as you do for slugs
