Hi all,  
I have been using Solr for a long time, they support multicore and  
configuration for each core is defined in xml files.  
I know that Elastic Search supports multiple indices and multiple  
types per index. From the document, I see that configuration for each  
index must be set through API. Is it possible to configure them in  
YAML or JSON configuration file, just like what Solr have done with  
multicore ?

Regards,  
Huy Phan

In any case you need to use the API to create indices, so you can simply add the settings there. You can have index level configuration in the elasticsearch.(yml|json) under the index section, and that will be inherited by all indices created, but, custom settings will need to go through the API.

The good thing with ElasticSearch compared to Solr is that you create  
separate types and indices. also the replication + sharding setup is  
very easy (see below).

So just create one json (or mapping via API) for every document type.  
Then create indices on demand (either one index per type or you can  
also mix them into one index):

curl -XPUT "[http://localhost:9200/yourindex/](http://localhost:9200/yourindex/)" -d '  
index :  
number\_of\_shards : 3  
number\_of\_replicas : 1  
refresh\_interval : 10s  
'
