Hello Arcadius, Noble,

I have a single Solr cluster setup across two DC's with below similar
configuration.  Now i am looking to use preferredNodes feature/rule that
search queries executed from DC1 client uses all dc1 replica's and DC2
client uses all dc2 replica's for faster query response.  I am bit confused
with the current documentation on what different steps needs to be taken
care on client and zookeeper side?  Can you  please summarize what needs to
be executed part of Solrj client configuration/properties and Zookeeper
clusterstate (MODIFYCOLLECTION) to make it work?

DC1 - 3-dc1 shards replica and 3-dc2 shards replica
DC2 - 3-dc2 shards replaca and 3-dc1 shards replica


Thanks,
Susheel
