How do you search for a specific song within a playlist?

So far I find Spotify unintuitive and lacking regarding the most basic features you'd expect from a music player app. 

By pressing CTRL + F I can only search for a specific artist. I would like to be able to search songs by words in the title. Is this feature non-existent at the moment? There's a search bar on the upper part of the interface. You'd expect that to be it, but no. Using that will search on the entire platform. Which is funny, I'm in my playlist, not the main hub.
