General :: Use Awk To Matching In Only A Specific Column?

Im trying to use awk to do matching in only a specific column

example.txt:
www.google.com www.example.com
www.google.com/search www.example2.com
i used:
awk '{ (if $1 == "http://www.google.com") print $2}' example.txt

this awk statement only returns the first line, and i cant seems to make it perform in a way to match based on keywords like GREP. Is there any way to make display the other lines which contains "google" also?
