Adding a search bar for videos in 7.1

I am currently using Squarespace 7.1 and I have page with a lot of videos that will serve as a "how to" library and I'd like to add a search bar for only that page, with results based off of the content I've written in each of the videos captions. 

Is it possible to do this?

It looks like you could do something similar in 7.0, when you were able to videos as a gallery but that doesn't seem to be available anymore.
