So I was going to search for unanswered questions with at least one answer which should be then of score 0 since the topic is unanswered.

According to advanced search I thought it should work:

closed:no isanswered:no answers:1


isanswered: yes/true/1 returns only questions that have at least one accepted or positively-scored answer; no/false/0 returns only questions with no accepted or positively-scored answers.

But the query returns accepted answers...

So is something wrong with my query or are such answers not enough to make question "answered" and the documentation is wrong?

p.s. answers:1+ in this case returns topics with 0 answers...


Somehow isanswered:no doesn't exclude questions with an accepted answer scored 0.

The following query should give you the desired search results:

isanswered:no closed:no hasaccepted:no answers:1


  • I suppose it is because the OR operator in no accepted or positively-scored, you can add it if you agree. – Kuba Nov 26 '15 at 9:13
  • @Kuba To me it also looks like that OR is programmed as an exclusive OR and I'd consider that a bug. – Karsten 7. Nov 26 '15 at 9:18
  • no no, I mean, that makes sense. All topics from my query have accepted answer of score 0 so it fulfills no accepted or positively-scored as 0 or 1 -> 1 – Kuba Nov 26 '15 at 9:20
  • @Kuba Ah OK, didn't read it that way. However I'd expect isanswered:no to be the opposite of isanswered:yes. – Karsten 7. Nov 26 '15 at 9:35
  • @Kuba I was reading it as no [(accepted or positively-scored) answer]. Whereas you and the search system seem to read it as (no accepted answer) or (no positively-scored answer). – Karsten 7. Nov 26 '15 at 11:37
  • Yes, I thought the same but then I changed my mind, just after posting the question. Still, not so clean convention imo so worth a topic. – Kuba Nov 26 '15 at 11:38
