Hi

I need change some fields created with `index` and `doc_values`with `false` for new value true. I'm working with Elasticsearch 8.5

```auto
{
  "analyzers": {
    "mappings": {
      "properties": {
         "pf1":{
           "type": "float",
           "index": false,
           "doc_values": false
          }
....

```

I've tried

```php
$params = [
           'index' => 'analyzers',
           'body' => [
               '_source' => [
                   'enabled' => true
               ],
               'properties' => [
                   'pf1' => [
                       "type" => "float",
                       'index' => true
                   ]
               ]
           ]
       ];

       $response = $client->indices()->putSettings($params);

```

But get error.

```json
{
	"error": {
		"root_cause": [{
			"type": "illegal_argument_exception",
			"reason": "unknown setting [index.properties.pf1.index] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"
		}],
		"type": "illegal_argument_exception",
		"reason": "unknown setting [index.properties.pf1.index] please check that any required plugins are installed, or check the breaking changes documentation for removed settings",
		"suppressed": [{
			"type": "illegal_argument_exception",
			"reason": "unknown setting [index.properties.pf1.type] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"
		}]
	},
	"status": 400
}

```

I think that I dont' understand well [Updating Mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html) or if change index and doc\_values are elegibles for update or I need to use another way.

You need to reindex this, you cannot just change the mapping parameters.
