"isanswered:no" returns questions with accepted answers [duplicate]

Question

According to the Search help, isanswered:no

returns only questions with no accepted or positively-scored answers

However, if I perform the following search:

isanswered:no closed:no answers:1

I get questions back that have an accepted answer.

In all cases, the accepted answer is scored 0 or lower.

However, I expected to get back no questions with accepted answers.

This seems to be a bug to me.

If it's not a bug, how can I search for questions with these criteria?

• one or more answers with none scoring greater than 0, and
• no accepted answer

Shadow Wizard points out that I can do this:

isanswered:no closed:no answers:1 hasaccepted:0

But shouldn't hasaccepted:0 be redundant to isanswered:no? If not, then the help text is misleading.

Answer 1

According to m0sa, the search parameter behavior is by design:

It's just named badly. Consider thinking about it as hasAnswerWithScoreGreatherThanZero.

Naming aside, I actually prefer the current behavior, because it gives me more flexibility in search. I can combine isanswered and hasaccepted parameters to get any combination of "answer with positive score" and "accepted answer" I want:

• answer with positive score: yes, no, doesn't matter
• accepted answer: yes, no, doesn't matter

If isanswered automatically included hasaccepted, the search possibilities would be fewer.

So I think it's the help center that should be fixed. Until recently, the parameter was not documented there at all. After my request The "isanswered" search parameter documentation is incorrect its description was added, but an incorrect one.
