Here is a problem , I have 3 ES nodes running , if one ES node gets down can we serve request from other ES nodes automatically . ---

If you use Java Client it will redirect for you. If not, you have to add a Proxy layer on top of your nodes (NGinx, ...).

Is it possible in query to send the request to more than two server?

Hi, typically query gets executed on more servers (where index or relevant shards are located) and aggregated on a single server and sent back to the client. So the query is distributed automatically behind the scene. Which server receives your query does not matter much (in most cases). Good elasticsearch clients can check for running nodes in the cluster periodically and notice if some nodes go away or are added into the cluster.

I want to explain a more here I wanted to say that suppose one server is down in a cluster and we are sending request request through [http://192.168.5.169:9200/raftaarsongs\_sdi/\_search](http://192.168.5.169:9200/raftaarsongs_sdi/_search) but I want that as other nodes are running the request can be serve from other nodes We are not using java client here is there any other way On Tue, Jul 10, 2012 at 4:05 PM, Lukáš Vlček [lukas.vlcek@gmail.com](mailto:lukas.vlcek@gmail.com) wrote: > Hi, > > typically query gets executed on more servers (where index or relevant > shards are located) and aggregated on a single server and sent back to the > client.

If your server is down, nobody will listen on 192.168.5.169 port 9200. So, who can redirect you ? So, as Lukas said, if you use another client than the official Java client, check that it supports also failover. If you are using CURL or your own implementation of HTTP GET/POST/..., you have to manage the failover on your side or to add a NGinx (or any proxy) on top of your ES nodes. David.
