Hi, We're considering moving our own lucene based distributed index and search system to elasticsearch. From tests I ran for 1 million indexed documents I get that elasticsearch is running faster, but when running tests on 26 million I get that elasticsearch is much slower. I ran the 1 million and 25 million tests in the following search configuration: 1 machine with 1 elasticsearch http node, 4 machines with 1 elasticsearch data node per machine (1 elasticsearch index with 2 shards and 2 replicas).
