I remember having troubles finding some creators by searching their name in the search field at the top of the page.
Right now, the only example I can find failing is “joqlepecheur”, which clearly exists ( https://joqlepecheur.itch.io/ ) but is not searchable by their name.
Other creator names, like myself “komehara”, when searched, will properly display the creator and also their created games (if main author, not just collaborator, but it’s enough).
I don’t know why this specific user is not searchable, I remember that others like “FluentlyStudios” were also very hard to find, now I can find them just typing “fluentlys” or “Fluently Studios” with a space. While “joqlepecheur”, “joq le pecheur”, etc. will all find nothing.
I’ll keep trying other names to see if other names are failing and if there is any common point between them.
I think it’s technical enough to deserve a GitHub issue so I’ll also make one.
EDIT: added space around brackets to avoid back link generation
