ElasticSearch Update Multi-field Mapping

Instead of PUT to /my_index do:

POST /my_index/_mapping

You won't be able to change the field type in an already existing index.If you can't recreate your index you can make use of the copy to field to achieve a similar capability.

   PUT /my_index        {          "mappings": {           "my_type": {        "properties": {                   "author":                    {                       "type": "string",                      "copy_to": ["author-name","author-ngram"]                   }                    "author-ngram": {                      "type": "string",                      "indexanalyzer": "ngram_analyzer",                      "search_analyzer": "keyword"                    },                     "author-name" : {                     "type": "string"                    }            }                        }       }     }  }

While I have not tried it in your particular example, it is indeed possible to update field mappings by first closing the index and then applying the mappings.

Example:

POST /my_index/_closePOST /my_index/_mapping{     "my_field:{"new_mapping"}}POST /my_index/_open

I have tested it, by adding a "copy_to" mapping property to mapped field.
