TL here. I don't use the search function on my email, but if I did and somebody's name came up I wouldn't really suspect them. Besides the only way for your ETL to prove it would be to pull security footage, zoom in on the screen or keyboard to see YOU typed it, and go from there. They'd also need to care enough in the first place to initiate all that. I've worked at a few different spots and w/several different AP's. None of them would be thrilled if an ETL came to them and said "So can you search through hours of footage to see who spied on my email? Pretty Please?".
AP would probably laugh her out the door.
Learn from your mistake, and move on.
