Thanks for the response Adrien. I'm excited to upgrade to 1.2, but it seems strange to me that people refer to scan vs. scroll (you're not the first) as scan is simply a search_type that - AFAIK - can be used for any type of search (scroll or otherwise).
It just seems strange that setting the search_type=scan changes the behavior of _search/scroll significantly (size=N semantics differ and no first page is returned).
