Searching for tags (ie, https://stackoverflow.com/questions/tagged/java%20-android%20-spring%20-hibernate%20-java-ee%20-c%2b%2b%20-c%23 ) leads to a broken RSS link (ie, the RSS link for the aforementioned search as linked from the RSS icon in my Opera address bar is https://stackoverflow.com/feeds/tag/java+-android+-spring+-hibernate+-java-ee+-c%2b%2b+-c%23 ) which may or may not return a 404 depending on which/how many tags are listed in the URL.
How can I get an RSS feed which filters by more than a few tags?
Why does a URL return a 404 depending on the tags?
