Viewing old games on a different device

For record's sake, I'd like to know when I played some games from my childhood, but I find that the games aren't there. I suspect I bought and played them around 2015-2018, and I have found other games I've purchased (back on my iPad Mini) but the older ones are not there. I see the date range search doesn't go past 2017, so do the records simply not go that far back?
