Query/filter by multiple ids

[Mestika]

I can't find any documentation on this but it would be great if it was possible to query or filter with multiple ids.
E.g. https://jsonplaceholder.typicode.com/posts?_limit=10&userId=2,5,10,12

following works for that kind of filtering
https://jsonplaceholder.typicode.com/posts?&userId=2&userId=5&userId=10&userId=12
