[BUG] <title> SortCombinations typings lacking interfaces/types

[logan858]

Describe the bug

I have a project where I'm converting from elasticsearch to opensearch, on a node/express server. (npm v @opensearch-project/opensearch@3.0.0-beta.3 )

I am noticing some (potential?) issues with the typings in this package, specifically the sort:

sortQuery:

my sortQuery func needs to return a SortCombinations compliant type object. In elasticsearch, the SortCombinations accomodates sorting by the field name with the SortOptions type like so:
es typings:

BUT, when we see the similar sort typings in os, it lacks the SortOptions of [property: string]: FieldSort | SortOrder | etc, etc. which allows the correct typings to be recognized for sorting by field names.

When using my own 'incorrectly' typed code it works perfectly fine to sort the opensearch results despite what the typings show , and in the opensearch docs it shows the functionality as one would expect:

Search

To Reproduce

1. Build an opensearch search query in ts/js.
2. and a sort object to the body
3. see typings mismatch

Expected behavior

typings should include field name sorting.

Additional Details

No response

my temporary local fix:

edit: (minus the format field, that doesnt seem to be supported by opensearch)

Thank you for bringing this to our attention. This incomplete typing for sort comes from the spec, which 3.x API is generated from. I've created an issue for it.

Closing as the spec has been updated and we're releasing beta.7 that includes the change.
