How to change search results page title?

Currently, my search page title formats itself like so:

search_term | Search Results | site_title

I would like the search results to be titled simply:

Search_term (Propercase)

How do I achieve this?

Thank you.

This isn’t Sage specific and we havn’t used wp_title in the theme since:

This means you’re best off referring to the standard WordPress resources such as the codex and WordPress development

Thank you for the information, I’ll go and see what I can find.

Ideally I don’t want ANY auto titling done as I will be doing it myself dynamically…
