What wrong with this Google site search?

[FromRocky]

No standard web pages containing all your search terms were found.
Your search - Site:mysite.com/ - did not match any documents.

A live web analytics from the site shows that there are an increase of references from Google today. So what was I doing wrong?

You used a capital "S" - site: is a special operator and it must be lower case.
