@dblock Added the changelog 😊 I'm yet figuring out how to add a test as there is not any test for any other filter as far as I can see

Yes, appreciate if you could write some for other filters as well, start with something simple and work from there. We have a testing guide: https://github.com/opensearch-project/opensearch-api-specification/blob/main/TESTING_GUIDE.md, too.

Since this is in the next version you will have to bump the docker hub ref in CI as well, https://github.com/opensearch-project/opensearch-api-specification/blob/main/.github/workflows/test-spec.yml#L29.
