file:lua$ search does not work with picker.grep

[drowning-cat]

Is it a bug, intended behavior, or a future request?

[folke]

that's not a bug.
grep uses live search by default, meaning the filtering is done by the underlying tool (rg) in this case.

You can grep first, then toggle live with <c-g> and start using the matcher with patterns like your exmaple.

I was a little bit confused because I was stupid enough to accidentally bind <C-g> somewhere in the window options. Thanks for the clarification—it works like a charm.
