Hi:
    I have a single node Elasticsearch instance running (version 1.0.0). 
This instance was configured 
with multicast false and no unicast IPs specified. and I change the default 
ports from 9200,9300 to 9600,9700 with 5 Shards and no replication.

I just added a new node to this instance like so :
on a new server, I used the same exact Elasticsearch version, with the 
configuration file copied over from the above instance, modified the 
unicast list of hosts to include the IP address of the above server 
instance. 

I started up the node instance with this configuration. I then checked on 
the cluster and saw the new instance being reported as an additional node. 
 I then used curl to up the replication factor to 2

My questions are these :

1. How long does it take for the data to be synchronized /distributed so 
that the data is available to be queried properly ?
2. Is the process I follow above flawed ? (are there any issues with it and 
Can I recover by stopping the cluster and restarting them with proper 
configuration set)
3. Prior to addition of the node, I was able to query for documents older 
than 35 days (now-35d)  but after the addition, this data is not available. 
 a query for match_all returns the right number of documents, except that 
the older documents do not seem to be query able . If the new node that was 
added goes away how is the data affected ?

Thanks for the responses and assists.

Cheers

Ramdev
