link: (space) mydomain.com

is a completely different search from

link:mydomain.com

so of course you'll get different results.

If you're researching links you want the one without the space. The other will simply show you instances where the words in your domain name happen to be mentioned, which might not even be you.

I baffled here, please help

I'd expect a poet to take more care with language than that...
