Thank you very much John and Garth, I've tested it out and it works fine, I can send the updates to any of the solr nodes.
If I am not using a zookeeper aware client and If I direct all my queries (read queries) always to the leader of the solr instances,does it automatically load balance between the replicas? Or do I have to hit each instance in a round robin way and have the load balanced through the code? Please advise the best way to do so.. Thank you very much again..
