Create or update mappings

Introduced 1.0

If you want to create or add mappings and fields to an index, you can use the put mapping API operation. For an existing mapping, this operation updates the mapping.

You can’t use this operation to update mappings that already map to existing data in the index. You must first create a new index with your desired mappings, and then use the reindex API operation to map all the documents from your old index to the new index. If you don’t want any downtime while you re-index your indexes, you can use aliases.

Required path parameter

The only required path parameter is the index with which to associate the mapping. If you don’t specify an index, you will get an error. You can specify a single index, or multiple indexes separated by a comma as follows:

PUT /<target-index>/_mapping
PUT /<target-index1>,<target-index2>/_mapping

Required request body field

The request body must contain properties, which has all of the mappings that you want to create or update.

{
  "properties":{
    "color":{
      "type": "text"
    },
    "year":{
      "type": "integer"
    }
  }
}

Optional query parameters

Optionally, you can add query parameters to make a more specific request. For example, to skip any missing or closed indexes in the response, you can add the ignore_unavailable query parameter to your request as follows:

PUT /sample-index/_mapping?ignore_unavailable

The following table defines the put mapping query parameters:

Sample Request

The following request creates a new mapping for the sample-index index:

PUT /sample-index/_mapping
{
  "properties": {
    "age": {
      "type": "integer"
    },
    "occupation":{
      "type": "text"
    }
  }
}
