Search Box – Right Alignment

Hello, i am a new user in Drupal and i have created a site using a Zen subtheme. The problem is that i can’t figure out how to move the search box in the right side of the header. I have searched a lot ,but most posts are fairly old. I am sorry if this problem has already been solved and i missed it.

Thank you!
