How can you integrate the Search engine into your Joomla site

To integrate the Google CSE, we first need to get the coding for the Custom Search Engine.
If you pushed "Finish", than you got a screen with one it the terms that says "control panel".

Choose here "Code"

You could start with the standard code, but this is only for testing purpose.
You can use this code to show the search results outside of your website.
Just try an example down below.

You can even set some simpel layout and logo.
But this is not really what we want, is it?
