machine_learning.start_trained_model_deployment - Adds new parameter cache_size (String) A byte-size value for configuring the inference cache size. For example, 20mb.
mget - Adds new parameter force_synthetic_source (Boolean) Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
search - Adds new parameter force_synthetic_source (Boolean) Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.

- order (String) Sort order (options: asc, desc).
- from_sort_value (String) Value of the current sort column at which to start retrieval.
- after (String) Offset identifier to start pagination from as returned by the next field in the response body.
