Is this code generated from spec (it should be)? I am afraid the bug is in the generator or the spec.

https://github.com/opensearch-project/opensearch-api-specification

If not, ensuring these descriptions are correct and making sure the API is properly represented in the spec would be grand.

Can you elaborate on that? Does it mean the the project doc is generated from this project and I should look for the bug there?

I was using the package when I noticed those spelling mistakes, so I'm unaware of the whole project ecosystem and details, any guidelines would be appreciated.

@m3et First, I merged this PR, thank you.

I found other instances of the same in another client, https://github.com/search?q=org%3Aopensearch-project%20onlymissing&type=code, if you are interested in fixing those.

Not yet, but it will be. We will need to merge descriptions between what's here and what's in the spec.

This was a bug in the generator, the next run undid all these changes.

I fixed it in https://github.com/opensearch-project/opensearch-py/pull/793/files#diff-999765094c323a96b13cc24c24aa13948be15e6beacda7747e83c300420f8018R626.
