How to do it...

The HTTP method to get a mapping is GET. The URL formats to get mappings are as follows:

• http://<server>/_mapping
• http://<server>/<index_name>/_mapping

To get a mapping from an index, we will perform the following steps:

1. If we consider the mapping for the previous recipe, the call will be as follows:

GET /myindex/_mapping?pretty

1. The result returned by Elasticsearch should be as follows:

{
  "myindex" : {
    "mappings" : {
      "properties" : {
        "customer_id" : {
          "type" : "keyword",
          "store" : true
        },
        "date" : {
          "type" : "date"
        },
        ... truncated ...,
        "vat" : {
          "type" : "double",
          "index" : false
        }
      }
    }
  }
}
