Regex in search field for global search blobs scope

Problem to solve

I've been searching if there is a possibility to search with a regex within the search field for the blobs scope in the global search.

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 downloading the project completely on my computer and do it by hand.

Further details

Proposal

If it is implemented, is it possible to add it in the documentation ?
