Today I found something interesting that exists in ElasticSearch. It's called Adaptive Replica Selection https://www.elastic.co/guide/en/elasticsearch/reference/6.1/search.html
Did you hear about it? Maybe exists something in SOLR? I think it's very useful for my case. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
