Solution 1:

Check registry fixes in this thread. That helped me.

To make sure it won't disappear I'm copying the solution from Martin Rosselle here:

Please check if the following registry key is ok. Fixing this solved the issue for me.

  • Copy the text below and save it as .reg file.
  • Go to regedit.exe and import saved .reg file or simply open the file with Registry Editor and click yes when prompted to continue.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}]
@="PSFactoryBuffer"

[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32]
@="C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\MSEnv\\TextMgrP.dll"
"ThreadingModel"="Both"

Solution 2:

I was able to solve this by running:

Devenv.exe /ResetSettings

from the visual studio command prompt, then running a repair on my visual studio installation.

Still a lengthy fix for such a simple problem, but not quite a reformat.

Solution 3:

See here: Visual studio search turned out to be a simple shortcut issue, Cntrl+Shift+F instead of Cntrl+F

Solution 4:

This is a known bug in VS that has been around since 2005. Click on the 'find results' box and click ctrl+break a few times.

If that doesn't work for you, there are a few other key combinations that should - take a look here:

No search results in visual studio
