How can I obtain the detailed mappings of a type?

I created a type with these mappings:

{
       "test" : {
                "_all" : {"enabled" : false},
                "_source" : {"enabled" : true},
                "properties": {
                    "a" : {"type" : "string","index" : "not_analyzed", "store": false },
                    "b" : {"type" : "double", "store": false },
                    "c" : {"type" : "date", "store": false }            
                }
       }
}

But when I try to retrieve the mappings I get this response from elasticsearch:

{
  "my-index": {
     "mappings": {
        "test": {
           "_all": {
              "enabled": false
           },
           "properties": {
              "a": {
                 "type": "string",
                 "index": "not_analyzed"
              },
              "b": {
                 "type": "double"
              },
              "c": {
                 "type": "date",
                 "format": "dateOptionalTime"
              }
           }
        }
     }
  }
}

Why has the store attribute dissappeared? Did I make a mistake in my PUT mapping?

When getting an Elasticsearch mapping it doesn't show the settings that have the default values.

The default is not to store individual fields (only the source document is stored) - test this by adding a field with store enabled:

curl -XPUT "http://localhost:9200/myindex/test/_mapping" -d'
{
   "test" : {
            "_all" : {"enabled" : false},
            "_source" : {"enabled" : true},
            "properties": {
                "a" : {"type" : "string","index" : "not_analyzed", "store": false },
                "b" : {"type" : "double", "store": false },
                "c" : {"type" : "date", "store": false },
                "d" : {"type" : "string", "store": true }
             }
 }'

getting the mapping shows that field d is stored.

curl -XGET "http://localhost:9200/myindex/test/_mapping?pretty"
{
  "myindex" : {
    "mappings" : {
      "test" : {
        "_all" : {
          "enabled" : false
        },
        "properties" : {
          "a" : {
            "type" : "string",
            "index" : "not_analyzed"
          },
          "b" : {
            "type" : "double"
          },
          "c" : {
            "type" : "date",
            "format" : "dateOptionalTime"
          },
          "d" : {
            "type" : "string",
            "store" : true
          }
        }
      }
    }
  }
}
