They wouldn't even have to add a real search function that looks through the database. Just add a text field that opens "https://herald.playphoenix.online/c/" + "name entered".
Click on any name on the herald and in the URL change their name to whatever name you want to search for and hit enter. pretty convoluted and obscure way to do a search why not have a search box on the main page? Its not a difficult thing to add.
