It depends.  Yes, you can use it in a way that avoids needing to clone
down repos and index them; in that case you're relying on the remote
instance.

Or you can clone and index the repos yourself and point lei at them.
You can do this with `lei add-external --mirror', but you still have to
update the repos yourself (see example at
<https://yhetil.org/emacs-devel/87wnh22w7o.fsf@kyleam.com>).

If you go the clone/index route, however, I'd recommend using grokmirror
to fetch Git repositories from public-inbox instances.  (In
https://issues.guix.gnu.org/43637#1 <878scww903.fsf@kyleam.com/>, I
provided an example config that mirrors Guix-related inboxes at
yhetil.org.)

For remote externals, `lei up' will pull in updates from the remote.
For local externals (things you've cloned down and indexed yourself),
you need to do something to pull in those update (e.g., a grok-pull or a
`git fetch').

I don't regularly used saved searches myself, so I don't know that I can
be much help, even if I had a clear picture of what you wanted in your
workflow.

Fwiw my setup is:

 1) use nntp via Gnus to skim new messages on mailing lists

 2) if I want to participate in a thread, use
    piem-inject-thread-into-maildir to get the messages into my local
    mail store and my Notmuch index.

 3) If I want to search for messages, I use lei-q via piem-lei-q.

    Using grokmirror and a configured pull.post_update_hook, I fetch
    updates for and index a subset yhetil.org inboxes that I want to
    have available locally for searching.

    (I use piem-inject-thread-into-maildir here too.)

I'd eventually like to be able to follow list with lei via piem's
interface, but things aren't there yet.
