Hi Upayavira, I believe there is a basic implementation of load balancing for distributed search. The submit() method in the HttpCommComponent class within SearchHandler contains code which splits a pipe character delimited string of shards and uses a LoadBalancedHttpSolrServer to send requests to them. But the functionality is limited to the features of the LBHttpSolrServer, such as round-robin choosing of shards to query (although when the string of |-delimited shards is split, the resulting individual shards are shuffled), so I'm sure this could be improved upon. Yes, thanks Alex, I see it now. My checkout of trunk was old, and clearly predated that code. I guess my question then is would a patch be accepted to backport it to the 3.x branch?

I've looked in trunk but cannot find anything that looks like it. Has this been implemented anywhere? If not, I'd like to have a go at implementing it. The requirements as I see it are: * randomised choice * on an exception, try other hosts for that shard, until exhausted More complex would be: * if a host is down, note it as such and try it again only after a pre-defined interval. Any thoughts?
