That's searching for files that are in the Go language but are flake.nix files - which is 0 results because flake.nix files are not written in Go.

This seems to work;

    path:/flake.nix go

I see, I thought it would be matching the repo's contained languages, not the file's language. Thanks for clearing that up for me.

Searching for "go" as a substring turns up a lot of false positives, but at least now I know the search is not flat out broken.
