Where did they go to? From Apple to Microsoft to SpaceX to Apple?

In addition what others have already said, in the Gmail search bar it can search for mails that have an attachment larger than x mb. I did that some time ago and there where a lot large mails that were not worth it to save on disk

Cool! How does it technically work? Does it fetch all titles (and maybe the body and comments) via the api from each instance or do you set up your own private instance and tap into the instance database?
