Does anyone know how to search for questions that were posted by a specific user and answered by another specific user? It seems that if there're multiple "user:id" in the search box, only the last one is effective.

@Saad SEDE. Is it possible to search for posts/questions of an user $X$ commented on/answered by the user $Y$?

BTW this would be on-topic in the searching chatroom. (Probably more than here.)

@BillDubuque I was hoping to look, but this link doesn't work for me. Typo? Or maybe something deleted out from under it.

Looks like both users may have already been dealt with. Which seems fine. The questions I did manage to get to were certainly non-questions.

@MartinSleziak Thanks! Btw, I didn't even know the existence of the chat room you mentioned :|

@GNUSupporter8964民主女神地下教會 This one looks OK now since the OP has added enough efforts.

Well, probably I should be more active in my effort to advertise that room. In any case, it has a separate answer in the post about chatrooms on meta: List of chatrooms.

@Saad Thanks for update! Close vote retracted.

@all This low-quality question has a bounty now.

@Saad flagged for moderator's attention since nobody can close it.

@rschwieb Yes, the mods seem to have handled the matter yesterday (the sockpuppet accounts were deleted and the main user was suspended for a month iirc).
