Thank you, Emir for your answer *But it will not send request to multiple replicas - that would be a waste of resources.* What if server is overloaded, but it is responsive? Then it will not be a waste of resources, because second replica will response faster then overloaded replica.
*and flag unresponsive one* Until when it will marked unresponsive? If solr will check it every request, it is also would be a waste of resources... -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
