Is there a way to get a list that combines two or more tags without all of the questions having to be tagged with both tags? For example, on stack overflow i tend to look at the sql-server tag a lot, but not all sql server questions get that tag. What i'd really like is a list of unique questions tagged with sql-server, sql-server-2005or sql-server-2008. Is there a way to do this? If not, can we implement a way to do this?

  • I think this actually used to work, I've got a collection of feeds, on of which points to http://stackoverflow.com/feeds/tag/emacs+or+elisp+or+emacs-lisp+or+dot-emacs that I used to keep up with, in this case, emacs questions. The feed doesn't seem to have been updated since October 29, 2010. – quodlibetor Feb 10 '12 at 16:58
  • I should point out, that going to http://stackoverflow.com/questions/tagged/?tagnames=emacs+or+elisp+or+emacs-lisp+or+dot-emacs&sort=active works, and has the standard rss link at the bottom, but that link goes to a 404. – quodlibetor Feb 10 '12 at 16:59

There is a data.SE query to do this for two tags:


which can be forked to work for three and base results on a specific state.


In many cases, a tag wildcard will do what you want. For your given example, [sql-server*] is the way to go; the * expands to all tags that fit that pattern.
