Dot notation syntax (`attributesToRetrieve` etc.) for arrays is not documented

@jkdoshi afaik this is not supported, but this will prices.price = 22 AND prices.per = "kg". Get me wrong @irevoire ?

I was looking for it for quite a bit. Maybe I missed it in the official docs? If I haven't this is a very valid issue.

I guess it is explained here how arrays are flattened, but I believe it would be better to explicitly state and give examples on how to use dot notation with arrays.

Hello, I moved your issue to the docs repository, as this looks like it is more pertaining to the documentation 👍

Thank you for reporting 🙏

Oh whoops, okay, sorry.

No problemo, I'm glad you reported, transferring to docs was a quick op 👍
