Get ES version:

  },
  "tagline" : "You Know, for Search"

Remove old index...
{

Make index and add some data - default mappings are fine
{

  "_type" : "type",
  "_id" : "1",
  "_version" : 1,
  "created" : true
}
{
  "_index" : "shardcache",
  "_type" : "type",
  "_id" : "2",
  "_version" : 1,

}

Wait for ES to be synced (aka refresh indices)...
