I've been testing concurrent queries, I have just one node in a server (1 * 4 core CPU, 12G memory) and create a index (4 shards, 1 replica). I use 1000 concurrent threads to query(use TransportClient, search condition contains a termFilter and sort in a field). I've found sometimes the testing could be finished, sometimes it cound't, because there are many EsRejectedExecutionException exceptions in ES log file.
