dovecot - Apr 2021 - Sharing a single solr server between multiple dovecot servers

I am brand new to solr and I'm interested in using sharing it between 
several dovecot machines I'm running. I'm looking for some big picture 
guidance on what I need to do to configure solr to work with the 
different dovecot machines. So far, I managed to set up a single 
"dovecot" core on the solr server and it is working with one of my 
dovecot machines.

I'm not sure how to proceed from here as I'm very unclear on how solr 
maintains separate indexes for different users on my different machines. 
Some basic questions I have are:

1) Do I need a new core for each of the dovecot machines I want to use 
with solr?
2) If not, how does solr ensure indexes for the different dovecot user 
do not get comingled?
3) If yes, how do I configure dovecot to tell it which solr core to use?

Thanks.

If the dovecot servers are serving same users, you can share the server.
If not, then you need to use multiple cores. Each core has it's own
entry point (URL).
