For some reason whenever I include the '(' character in a Ctrl + F search in Visual Studio 2013 the search bar never works. It doesn't matter what other text is included in the search bar. It doesn't matter if I choose to search on just the current document, or the entire project.
If I search on anything else that doesn't have a '(' character then Ctrl + F works just fine.
When the Ctrl + F search doesn't work I see a blue 'progress' line moving through the bottom of the search box the entire time, as if it's doing something, and I can hit the 'X' next to the search textbox to stop the search, but no matter how long I wait I never get any results back.
I haven't installed any add-on's to Visual Studio recently, so I'm not sure what could be causing this.
