This question already has an answer here:

I'm trying to find unanswered questions with both kotlin and gradle tags like this: https://stackoverflow.com/unanswered/tagged/kotlin+gradle

It shows many questions without kotlin tag which is unexpected.

All questions with url like /questions/tagged/kotlin+gradle works correctly.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


It has been made clear that using the phrases: [kotlin][gradle] (tags that have "kotlin" or "gradle"), kotlin+gradle (tags that have in them "kotlin" and "gradle"), kotlin+gradle (all search terms that have "kotlin" and "gradle") do not show only unanswered questions.

I think this is because the unanswered page description says "questions with no upvoted or accepted answers tagged with", that is, it mixes questions with no upvotes and no accepted answers, so at the moment, there is no clear way to separate this list into only unanswered questions.

In short, there is no official way to do what you asked for, unless you use @Ilya's workaround.

Note: I put this link to show demonstrate how the site mixes other types of questions with unanswered questions, and also to show that it works for other keywords as well.

  • Not relevant. When adding a search term (i.e. typing anything that is not a tag in the search box), the user is redirected to the general tag search/page, and leave the Unanswered section, which the question here is all about. – Shadow May 11 '17 at 9:34
  • I don't think that the OP is asking anything that is not a tag, but the OP wants to know how to search for questions that are tagged with multiple tags combined together. If this is not their intent, then can you please support your claim with evidence? – Toby Mak May 11 '17 at 9:37
  • "I'm trying to find unanswered questions" - see bold part. There is whole section on SO for unanswered questions, separate from the ordinary questions section, and that's the point. – Shadow May 11 '17 at 10:00

  • Never mind, you miss my point and I can't explain it any better. – Shadow May 11 '17 at 10:24
