Maybe it is useful to mention also that search modifier
user:me restricts the search to
my own posts. And if you go to
a user profile then the
user:userid
part is already prefilled in the top bar. (And this is also the way to find userid.) Let me know whether you prefer that I post a separate answer with adding these details or whether you add them to your own post. —
