I don't think there is much use of having one service that serve us with
users and another service that serves us with information about those users
and has search service. It should be one and the same IMO.
How it is constructed internally is another question. It is obvious that it
will be good to havethe possibility to separate the storage of user ids and
their meta-data like in the examples you had.

I don't see how that would be possible, actually.
