As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
