Hi,  
I am learning use ES now.Today when i sent request to the ES i get  
some problem.  
I want create a index named "test".So I followed the demo on the  
elasticsearch.org.

$ curl -XPUT '[http://localhost:9200/test/](http://localhost:9200/test/)' -d '{  
"settings" : {  
"index" : {  
"number\_of\_shards" : 3,  
"number\_of\_replicas" : 0  
}  
}  
}'

The index was created successfully.But Why was the setting useless? There were also 5 shards and 1 replicas in the index.

This works correctly for me.

Are you sure the index didn't already exist?
