Nice!

I think we should rename and organize the .yaml test filenames into folders consistently with the keywords used.

• tests/default/_core/search/terms_query_field.yaml is a query with terms, so tests/default/_core/search/query/terms.yaml
• terms_query_multiple is a variation of the first one, so you should combine them
• terms_set_query is a query with terms_set, so it becomes query/terms_set.yaml

Generally we're not testing OpenSearch, just the schema. No need to test response bodies.

Finally, we also plan to use these tests to auto-generate documentation, so consistency becomes important (too many docs are all over the place when it comes to kinds of examples) - try to simplify these tests as much as possible. Try only using our canoical movies and games examples used elsewhere instead of introducing new types of things (classes, students).

I have some more nitpicky comments, see which ones make sense to you.

A lot of this can be replaced with a much shorter version with _bulk. Look for it in other tests.

Thanks @dblock I have updated the PR addressing your comments, please take a look.

Tiny nit of ,<space>.

If you're looking for more work @prudhvigodithi, #548 looks like it's a bit more involved, might also need doc fixes.

[prudhvigodithi]

Sure @dblock.
Thanks
