Currently I hafer over 50+ millions documents at my index and as I mentiod before at another question I have some problems while indexing (jetty EOF exception) I know that problem may not be about index size but just I want to learn that is there any limit for document size at Solr that if I exceed it I can have some problems? I am not talking about the theoretical limit.
What are the maximim index size for folks and what they to handle heavy index rate when having millions of documents. What tuning strategies they do? PS: I have 18 machines, 9 shards, each machine has 48 GB RAM and I use Solr 4.2.1 for my SolrCloud.
