Request: Document the isanswered search parameter on the advanced search help page.


This has been implemented by adding the following to the help page:

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.

Unfortunately, the above is incorrect: acceptances are ignored by this search. The correct description would be:

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


From time to time users ask about searching for questions that are unanswered-in-SE-sense (no accepted answer and no positively scored answer). For example, Deduplicator asked yesterday:

What about adding a new operator to search, which restricts the same way as the unanswered page?

The older thread on this is How to search unanswered questions where the answers include: using hasaccepted:0, using answers:0. There is also a feature request there to have ascore:0 parameter to handle the presence of answers with positive score.

Yet, all this time SE did have a search parameter for filtering questions based on answer score: isanswered. As m0sa explained, its logic is actually hasAnswerWithScoreGreaterThanZero

Thus, the combination isanswered:0 hasaccepted:0 closed:0 matches SE definition of an unanswered question.

For example, this search nearly matches the questions/unanswered view on Stack Overflow. (The numbers are not exactly the same, either because of caching or because of some narrow edge cases; for practical purposes the results are the same.

One can now filter by tags and/or question score, then sort by dates, etc... like you always wanted. For example, when I'm feeling generous, I combine this search with intags:mine and answers:1.. to review answers on unanswered questions and maybe upvote them, taking the question out of unanswered.

    The other option is to fix the search parameter.

I've updated the documentation to describe the actual behaviour of the isanswered search operator, which does not take the accept status into account.

  • hi, I was trying to use the is:answered filter and since it was not acting like I expected, I started looking around and it all lead me here, so I tried changing my search criteria and tried [jquery] created:31d answered:0 is:question and [jquery] created:31d answered:...0 is:question only to be disappointed again: either way results show 1 question, specifically, and this is the results' url; am I missing something?, again?
