when multiple queries exist, how are they executed? for example, like scraped photos: 2 queries - tag1, tag2 1, does it go through tag1 posts before hitting tag2? or randomly going beween tag1 and tag2? 2, i assume it goes from the top down, meaning it starts from the newest post (except top posts) and works its way down. what happens when there are new posts coming in during the process? i suppose there is no way of skipping old posts (e.g., 3 days or older)? no way of skipping top posts?
