Well I am trying to sort a collection of backups to make some sense of it, I am trying to find files where I dont always know the full name.
Exactly!
As Ignatzatsonic said, you just start typing whatever you remember of the name. Can be the start of the name, the middle of the name, a portion of the name, drive/folder limited, * wildcard types, etc.
As you type the Everything index is simultaneously being examined and the Explorer-like presentation "hit list" appears in the window area below. The more precise is your file name, presumably the smaller and more refined is the "hit list".
You specify what drives you want Everything to "watch over" and as long as it's running (which starts when Windows starts) the real-time index on every single partition you've included is real-time updated as you work. Every file add, change, delete, rename, etc., the Everything index is simultaneously and instantly made current. You will not see any overhead at all.
You can also use the "hit list" to open files (double-click or right-click context menu, just like with Explorer).
Try it. You'll like it, I'm sure.
It is EXACTLY what we all wanted, for pure file name searching.
