Re: Understanding the difference between two queries

The difference between a [site:example.com] and a [site: example.com]
(note the space between site: and the domain!) is that the first shows
only pages from that site, provided there are no hijacking issues, and
the latter shows pages containing the site's URL, what is not equal to
a link. The [link:example.com] search is absolutely pointless, it may
show inbound links or not, and if so, only a useless set of outdated
samples.
