It’s complicated.  As it stands, I’d rather not add overhead to ‘guix
pull’, especially since current ‘guix search’ on my SSD is fast enough
and can hardly be made any faster.

Realistically though, I understand that things are different on slower
machines and/or spinning disks.  That’s why I’m interested in seeing how
Arun’s proposed changes can affect such machines.

If, as a bonus, it allows us to have an inverted index and thus improve
the quality of search results, that’s great!

Thanks,
Ludo’.
