Why Google Search Shortcuts (like info: …) may don’t work for some of my sites?
Can you give an example?
When I put in google
info: www.mysite.pl
or
link: www.mysite.pl
I get listed many sites but not mine…
There shouldn’t be a gap between the : and your site URL, try that.
e.g.
info:www.yoursite.com
That’s right! Thanks 
You’re welcome
