Thank you, Emir for your answer
*But it will not send request to multiple replicas - that would be a waste
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
*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...
