Hello - what is the fundamental limitation for which we can only use one index for one collection ? The use case to have different schemas for the same set of documents would be to allow querying the same set of docs while controlling for access rights. For example, when searching for news, you would only be able to go through the title if you have not subscribed, but also the content if you have subscribed. You would also control what the response contains at the same time (send the content if subscribed, do not if not subscribed)
