As Alexander Ivanov wrote,

Yes, I'm understand that this topic has resolved. But I found something fancy!

P.S.: Please, if somebody knows why it works then comment.

Google uses their own re2 regular expressions engine. Using (?i) is allowing you to set the flags for case insensitive search https://re2.googlecode.com/hg/doc/syntax.html
