Hello Linux Geeksters.

In this article I will show you how to disable the Amazon search results, from the Unity Dash in Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin.
In the latest Ubuntu versions, when you search things in the Unity Dash, you also get shopping results from Amazon.
To disable this service, you have to remove the unity lens shopping package or turn off online search results from the privacy settings.
Type Privacy Settings in the Unity Dash, and turn off “Include online search results”.
To remove unity-lens-shopping from Ubuntu 13.04, 12.10 and 12.04, do this:
$ sudo apt-get remove unity-lens-shopping
For the modifications to take effect, use this command:
$ unity --replace &
Or Reboot:
$ sudo reboot
