How do you search for a particular extension on google?

I used to know how to do that and my mind has gone blank. lol

Like, only results for .net .us .org and so on.

Nevermind my mind came back to me.

site:.com site:.net and so on...

There, you can go to "Occurences" drop down to select "in the URL of the page" then type the extension in the box below.

Cheers
