Hi, from my experience when you have to scale in the number of documents it's good idea to use shards (so one schema and N shards containing (1/N)*total#docs) while if the requirement is granting high query volume response you could get a significant boost from replicating the same index on 2 or more machines and do load balancing on those machines (consider that in most cases a "round robin" LB works pretty well). So I think you should look inside the replication wiki page [1]. To check your Tomcat installation the related wiki page may also be useful [2]. My 2 cents, Tommaso
