Size support in elasticsearch _suggest

Elastic Stack Elasticsearch

By default elastisearch _suggest returns 5 suggestions matching the criteria.Is it possible to extend that to more than 5, atleast 10 suggestions. I tried size just like in other queries and seeing below error. any thoughts?

"reason": "[suggest] does not support [size]"
