URL for unanswered questions containing any one of tags, sorted by newest

Question

I searched around meta but did not find an answer that fulfills what I'm looking for.

I would like to see a list that:

1. contains only unanswered questions
2. is sorted by newest first
3. each question matches one or more of a list of tags (that is, A or B or C).
4. can be accessed with a URL from stackoverflow.com

I tried Stack Exchange filters which doesn't seem too flexible.

This one came closest, but it searches questions containing both excel and vba. I don't know how to apply "OR" keyword instead. Simply inserting OR into the URL returns no results.

https://stackoverflow.com/search?tab=newest&q=[excel]%20[vba]%20answers%3a0

Works for excel and vba and now Broken when I naively add OR

I also ran into something like this:

https://stackoverflow.com/questions/tagged/css%20or%20javascript but it is sorted by votes. How can these two functionalities be joined?

Answer 1

Easy enough to do.

You start with the main unanswered tab:

https://stackoverflow.com/unanswered

Then you filter out the tags you're interested in; instead of /questions/tagged/x, it'll be /unanswered/tagged/x. You can search for multiple tags by combining them with "or".

https://stackoverflow.com/unanswered/tagged/vba+or+excel

Then you sort by newest:

https://stackoverflow.com/unanswered/tagged/vba+or+excel?tab=newest
