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

An image to applications is shown like this, when looking at Ubuntu dash search feature.

    I think you're talking about the Ubuntu dash search engine. You can upload a picture and leave only a link to it.

Try to remove and re-install unity-lens-applications

sudo apt-get purge unity-lens-applications    
sudo apt-get install unity-lens-applications

Edit: Log off & login. If doesn't work restart your system (see comments)

I finally found out why the installed Applications were not showing up. Check for Filters options while searching and select the Applications button.

Mine was not selected so it was listing due to filters applied.

I had this problem. To solve it i deleted the recent files I had downloaded that were not on the software centre (i.e livewallpaper and the files related), used 'sudo apt-get autoremove' and then 'sudo reboot'.
