# Create or update mappings
|
||
Introduced 1.0
|
||
{: .label .label-purple }
|
||
|
||
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]({{site.url}}{{site.baseurl}}/opensearch/reindex-data) 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]({{site.url}}{{site.baseurl}}/opensearch/index-alias).
|
||
|
||
|
||
## 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.
|
||
|
||
```json
|
||
{
|
||
"properties":{
|
||
"color":{
|
||
"type": "text"
|
||
},
|
||
"year":{
|
||
"type": "integer"
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
## Optional request body fields
|
||
|
||
### dynamic
|
||
|
||
You can make the document structure match the structure of the index mapping by setting the `dynamic` request body field to `strict`, as seen in the following example:
|
||
|
||
```json
|
||
{
|
||
"properties":{
|
||
"dynamic": "strict",
|
||
"color":{
|
||
"type": "text"
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
## 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:
|
||
|
||
```json
|
||
PUT /sample-index/_mapping?ignore_unavailable
|
||
```
|
||
|
||
The following table defines the put mapping query parameters:
|
||
|
||
Parameter | Data type | Description
|
||
:--- | :--- | :---
|
||
allow_no_indices | Boolean | Whether to ignore wildcards that don’t match any indexes. Default is `true`.
|
||
expand_wildcards | String | Expands wildcard expressions to different indexes. Combine multiple values with commas. Available values are `all` (match all indexes), `open` (match open indexes), `closed` (match closed indexes), `hidden` (match hidden indexes), and `none` (do not accept wildcard expressions), which must be used with `open`, `closed`, or both. Default is `open`.
|
||
ignore_unavailable | Boolean | If true, OpenSearch does not include missing or closed indexes in the response.
|
||
ignore_malformed | Boolean | Use this parameter with the `ip_range` data type to specify that OpenSearch should ignore malformed fields. If `true`, OpenSearch does not include entries that do not match the IP range specified in the index in the response. The default is `false`.
|
||
cluster_manager_timeout | Time | How long to wait for a connection to the cluster manager node. Default is `30s`.
|
||
timeout | Time | How long to wait for the response to return. Default is `30s`.
|
||
write_index_only | Boolean | Whether OpenSearch should apply mapping updates only to the write index.
|
||
|
||
#### Sample Request
|
||
|
||
The following request creates a new mapping for the `sample-index` index:
|
||
|
||
```json
|
||
PUT /sample-index/_mapping
|
||
|
||
{
|
||
"properties": {
|
||
"age": {
|
||
"type": "integer"
|
||
},
|
||
"occupation":{
|
||
"type": "text"
|
||
}
|
||
}
|
||
}
|
||
```
|
||
{% include copy-curl.html %}
|
||
|
||
#### Sample Response
|
||
|
||
Upon success, the response returns `"acknowledged": true`.
|
||
|
||
```json
|
||
{
|
||
"acknowledged": true
|
||
}
|
||
```
