Is there a way to use this plugin with attachment type?

@jprante that's perfect.

One more request I would need to store the language code using "store": "yes":

PUT my_index
{
  "mappings" : {
    "docs" : {
      "properties" : {
        "file" : {
          "type" : "attachment",
          "fields" : {
            "file" : {
              "type" : "multi_field",
              "fields" : {
                "file" : {
                  "type" : "string", 
                  "store": "yes"
                },
                "language" : {
                  "type" : "langdetect",
                  "store": "yes"
                }
              }
            }
          }
        }
      }
    }
  }
}

Resulting mapping does not show store: true:

{
   "docs": {
      "properties": {
         "file": {
            "type": "attachment",
            "path": "full",
            "fields": {
               "file": {
                  "type": "multi_field",
                  "fields": {
                     "file": {
                        "type": "string",
                        "store": true
                     },
                     "language": {
                        "type": "langdetect",
                        "fields": {
                           "language": {
                              "type": "string"
                           },
                           "lang": {
                              "type": "string"
                           }
                        }
                     }
                  }
               },

Is that possible?

[jprante]

Sure. You have to treat the langdetect type like a multifield.

Like this:

curl -XPUT 'localhost:9200/test'  -d '
{
  "mappings" : {
    "_default_" : {
      "properties" : {
        "content" : {
          "type" : "attachment",
          "fields" : {
            "content" : {
              "type" : "multi_field",
              "fields" : {
                "content" : { "type" : "string" },
                "language" : { 
                   "type" : "langdetect",
                   "fields" : {
                      "language" : { "type" : "string", "store" : true },
                      "lang" : { "type" : "string", "store" : true }
                   }
                }
              }  
            }
          }
        }
      }
    }
  }
}
