Parsing of newest unanswered C++ questions seems to have broken
Am I using StackExchange incorrectly? I start by looking at all unanswered questions at this URL: https://stackoverflow.com/unanswered
There, I filter for "visual-studio-2010" questions by clicking on the gray chicklet in the right-hand column. I end up at this URL, and that seems fine: https://stackoverflow.com/unanswered/tagged/visual-studio-2010 AT this point, I can see "3,901 questions with no answers tagged with visual-studio-2010".
I further want to filter to questions involving visual studio and C++, so I click the "c++" chicklet in the right-hand column. That takes me to this URL: https://stackoverflow.com/unanswered/tagged/visual-studio-2010%20c%2b%2b
But the thing is I'm looking at "questions with no answers tagged with 'visual-studio-2010' 'c'". Note that's 'c', and not 'c++'.
Am I don't something incorrectly?
