As much as I saw, no need for different capitalization, if you type all with small letters, the capital ones will also show. Why would you even think that it's case sensitive?
So in your case, I only typed "galner", and I could see all those variations where "galner" was mentioned, capital or small.

Bug or an error noticed.
On the artist page in Ignition, https://ignition4.customsforge.com/artist/1299 it shows images (avatar and cover) for some other artist. Usually it show the album cover of the first ever added cldc of that band, but it's not that case, either. Unless that first cdlc was edited at some point, and it somehow had a wrong image at first. And now I saw that the spotify link for the cdlc Balkan is also showing some unrelated band, maybe becuse it's not on Spotify?
