I lost a function and can't find it

So some days ago I made a simple clock for my game hud. But my issue is that I can not find it anywhere in my blueprints :D. All I kinda remember is that I used tick for it and it has some variables I made for it. The function I used to display the time was called “print text” and it had some variables for it too.

Here is a screenshot that shows the clock on the screen. So it works.

(probably not a very helpful image)

So is there a way to search for a variable by name from all the project variables for example? Or search for a function from all project files?
