Feature request: Email search support and user inputted data search support

I'm finding it nearly impossible to browse the hundreds of purchases to determine if someone genuinely purchased one of my products or not, and the information provided by email isn't search compatible.

Gumroad's purchase notification emails support search by the data input at checkout.

It would be incredibly optimal and appreciated to have both capabilities, since at my current size I can't spend hours looking for an email that doesn't match with account information or the discord usernames added at checkout.
