seems neat code wise, but taking a step back, what is the problem we're trying to solve here? Like what is the intended user experience we are fixing?

I just made multiple queries for example and got back an error:

but honestly I'm not terribly confident I understand what the experience should be for multiple queries you know?

Closing this after thinking about this line:
const er = new OpenSearchResponse([target], res);
and realizing it would probably be not so simple to extract responses that are in response.aggregations and response.hits that correspond to the respective queries. That is, without refactoring OpenSearchResponse.ts and probably making it more unreadable.
I think this PR is a less impactful solution for now
