export ELASTICSEARCH_SERVER_URL=http://localhost:9200

create index and put mappings

curl -XPUT '$ELASTICSEARCH_SERVER_URL/wherehows_v1' --data @index_mapping.json

create index alias Using aliases has allowed us to continue using elasticsearch without a huge operational nightmare this allows switching transparently between one index and another on a running cluster Here we use wherehows as alias for different versions, newer indexes such as wherehows_v2 can be created, populated and then points to wherehows, as a public index interface

curl -XPUT '$ELASTICSEARCH_SERVER_URL/_aliases' -d '
{
  "actions": [
    {
      "add": {
        "index": "wherehows_v1",
        "alias": "wherehows"
      }
    }
  ]
}'
