How can i put search keywords in title of resultant page ?

For log checking and adding bookmarks relevantly
I need to change the page title of resultant page.

How can i put search keywords in Page title like:
Search | keyword1 keyword2 | example.com

(I tried to do this with Page Title module, but i should select a content type. So i couldn't do by that way.)

How can i do this?
Thank you.
