Adding Program to Ubuntu Search
Refer: https://askubuntu.com/questions/285951/how-to-add-programs-to-the-launcher-search
ONE:
Install a program called 'Alacrity' or 'Main Menu' from the software center. It will create launchers as you desire. It is that "add to launcher" program you are looking for.
TWO:
You can create a .desktop file (same thing as a launcher), and place it here: ~/.local/share/applications
I believe the format for a .desktop file goes something like this:
[Desktop Entry]
Type = Application
Name = name-of-application
Comment = your-desired-comment
Exec = command to execute (ex. 'eclipse')
Icon = path-to-icon
