Regex in search field for blobs

Hello !

I've been searching if there is a possibility to search with a regex within the search field. I want to search for a specific chain of character inside my project files, but i can't find a way to do it without download the project completely on my computer and do it by hand.

Example : https://gitlab.com/api/v4/projects/<project_id>/search?&scope=blobs&search=<_regex_>

Thanks by advance for your answer :)
