I just saw a ruling precedent. Take note Asian players. If you used a searcher and accidentally saw more than the mentioned number of cards, it won't result to a game loss. 

The judge will show the card to your opponent and put it in the bottom. This is what the JP Judge did.

Witnessed a game before where the player received a match loss because of this. We even joked that they took more time shuffling their decks than playing because it's a turn 1 Izou lol.
