title	CURL command & more information

Create a new Index with a unique name.

The creation of the new Elasticsearch index allows for the optimization of the working index for the current storage requirements. Indices work best when storing around 10 GB, and should contain no more than 50 GB of data.

For a cluster than contains 50 GB of Elasticsearch data, a high-performance index might look something like this:

collapse	true

curl -X PUT "localhost:9200/yuuvis_2?pretty" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "index": {
      "number_of_shards": 5, 
      "number_of_replicas": 1 
    }
  }
}
'

Make sure to change the index parameters to suit your storage and reliability requirements.
