On the index settings page of the documentation there is no mention of the index.sort.* settings. They were introduced in ElasticSearch 6.0 (“Introducing Index Sorting”) so OpenSearch should have it. Also in the OpenSearch repository there’s code referencing this feature.

I haven’t tested yet but I hope index.sort.* would be available since it will definitely help index performance for my use case. It would be comforting to see some reference of these settings in the docs if they are indeed supported.
