Tell me how to make the ubuntu search engine half the screen?
Example:

Answer 1

Goodnight.
Try to execute in the terminal (not full screen)
or
the last command should expand to full screen.
You can use the "MyUnity" utility, on the "dash" tab you can adjust the window size.
ps When the dash window is open, there is a button in the upper left corner that minimizes/expands the dash window.
