Books with Pascal case (or camelcase) such as HellSans (https://app.thestorygraph.com/books/ee523633-678d-41bf-aa4e-e6ff01adc78b), are difficult to find, even when using the correct case. See screenshots for searches using all lowercase letters, only upper case for the first letter, and the correct case. Oddly, the only way I could find this book was by searching "HellSa".
