#|
||Field | Description ||
|| page_size | **int64**

The maximum number of results per page to return.
If the number of available results is larger than `page_size`, the service returns
a [ListResourcePresetsResponse.next_page_token](#yandex.cloud.mdb.opensearch.v1.ListResourcePresetsResponse) that can be used to get the next page of results in subsequent list requests.

The maximum value is 1000. ||
|| page_token | **string**
