The SE definition of "answered" question is: has an answer that is either accepted or has positive score. But the search parameter isanswered appears to ignore the "accepted" clause: when set to "no" it still returns questions with an accepted answer, as long as it has 0 score.

Sample query to reproduce the bug (unless meta effect kicks in and the answers get upvotes).

By the way, it seems that isanswered works only when is:question is present, but I'm not complaining about that... yet.

Also, this parameter is not listed on the advanced search help page, but I'm not complaining about that either... yet.

  • isanswered works if you're searching for those that aren't unanswered, as the tab defines it

  • No. The unanswered tab does not list questions with an accepted answer. The parameter isanswered:no does.

That is the flag we use for the unanswered tab. It's just named badly. Consider thinking about it as hasAnswerWithScoreGreatherThanZero.
