Q:

How to find unanswered questions for specified tags

I have gone through How to get questions which exclusively match only the specified tags? but could not get understand it.
Is there any URL for Stack Exchange sites, from which further information can be explored?
At the moment, I am interested in unanswered questions for following tags: metro, windows-8.

A:

It's the same URL format except with /unanswered instead of /questions.
To get either tag, use https://stackoverflow.com/unanswered/tagged/metro-ui+or+windows-8.
To get both tags, use https://stackoverflow.com/unanswered/tagged/metro-ui+windows-8 (the "and" is implicit, unlike "or").
