Different ways to search for inbound links in Yahoo

what's what?

Recently I found a study about the different ways to search for inbound links in Yahoo.

I'm curious about the different syntaxes and what they do. Does anybody know?

link = inbound links to the domain
link:http://site.com = all inbound links

link:http://yahoo.com = 269,000 (missing www)
link:http://www.yahoo.com = 15,000,000 (links to home page)

linkdomain:yahoo.com = 138,000,000 (to any page of the site) (drop http & www)

linkdomain:www.yahoo.com = 15,800,000 (drop http, add www)(to any page of the site using www?)

linkdomain:yahoo.com -link:http://yahoo.com -link:http://www.yahoo.com = 123,000,000 (links to the whole domain, minus the home page)

linkdomain:www.yahoo.com -link:http://yahoo.com -link:http://www.yahoo.com = 883,000 (using www)

linkdomain:yahoo.com -link:http://yahoo.com -link:http://www.yahoo.com -site:yahoo.com = 98,700,000 (without www)

Any ideas?

It looks to me like yahoo includes sub-domains for the linkdomain so that linkdomain:yahoo.com includes yahoo.com, mail.yahoo.com, www.yahoo.com, etc while linkdomain:www.yahoo.com most likely only includes www.yahoo.com because there are no foobar.www.yahoo.com subdomains.

After that my head spins, but your suggestions seem to add up correctly.
