I got this question in review. First sentence is:
I know there is a same question, but no answers.
And indeed the two questions are virtually identical. I started to flag as duplicate - but the original question had no answer at the time, so it wouldn't be correct and apparently not even possible. (I didn't go so far as to try to submit the flag).
What is the proper action here? How do we want such a question to be handled? Should both (or more) questions stay open indefinitely until either is answered and somebody gets the good idea to do the duplicate linking?
As the new question is essentially a bump to the front page (perhaps with re-tagging), especially in the case where the OP knows that a previous question exist, perhaps something should be done to enable
bumping re-emphasizing without writing the new question.
As I wrote this, the new question actually got an answer. So the old one should now be closed as a duplicate of the new - but my question remains for the case where all known/found duplicate questions have no answer?
Ironically, just before asking this, the "Questions that may already have your answer" gave me this... (Although the suggestion has no answer). So it has been asked before - the comment there even suggest the ability to re-emphasize.
