Glad to help. Yeah, I thought you might have been making it harder than it needed to be ;). In SolrCloud you're constantly running up against "it's just magic until it's not", knowing when magic applies and when it doesn't can be tricky, very tricky. Basically when using LBs, people just thro

Thank you, Erick. That confirms our understanding for a single cluster, or once we select a node from one of the two clusters to query. As we try to set up an external load balancer to go between two clusters, though, we still have some questions. We need a way to determine that a node is sti

Multiple clusters with the same dataset aren't load-balanced by Solr, you'll have to accomplish that from "outside", e.g. something that sends queries to each cluster. _Within_ a cluster (collection), as long as a request gets to any Solr node, sub-requests are distributed with an internal softwar
