Hello @everttconsidin, welcome to the Seller Community!
This is a good question that I can help answer 🙂. You can search by notes on the Square Dashboard. Just head to the Sales Tab and your Transaction Report. You should see a filter at the top that says "Card #". Select "Note" from the drop down and type in your customers name to the search box on the right.
If you need help finding this filter feel free to reach out to me!
