I have a weird issue with Unity, it just stopped showing applications in the unity dash search menu.
I can't launch application unless I run them from the terminal.
I have tried to force unity re-installation with no success, and I could not find any other information regarding to this issue. Prior to full re-installation (I prefer not to, since my disk is encrypted) I am seeking for help. (I am a developer and would love to help with more information as needed).
An image to applications is shown like this, when looking at Ubuntu dash search feature.

Try to remove and re-install unity-lens-applications
Edit: Log off & login. If doesn't work restart your system (see comments)
