The bug #1238979 improves the situation with updates to the results
model, but it doesn't solve the problem of poor connection.
For this to be possible I think we will need cooperation from scopes,
because only the scopes know if all the data they serve comes from
network and if old results should be preserved if network is not
available. Scopes currently receive connectivity status with every
search, so they can use push_surfacing_results_from_cache() method of
the SearchReply to push the old results again without any extra work. We
could make it even easier for scopes to handle this by enhancing
CompletionDetails in scopes API with a new status such as
InternetRequied (displays appropriate banner to warn the user) or
InternetRequiredAndKeepTheResults (banner + keep old results on the
screen) - but are easy to implement in the shell, but the bulk of work
would be to update scopes to use it.

The scopes content disappears completely when you try to refresh it
when using a poor internet connection, because it blanks the previous
content without giving any new ones (until you get a proper connection
again).
This produces a really bad user experience because the user ends up
with a set of blank scopes, without any content (while the previous
data could be useful in some way).
As a user I'd expect the data to be dynamically updated (visually at
least) as you get them, with a proper notification for the user.
