limit Start Search to local files

I find that when I hit the Start button and it gives me a list of files
many of them are files up in the cloud on Dropbox.
I would like to only be offered the choice of files local to my PC.
Is there a way to limit the search?
TIA

 

The search has a control panel called Indexing Options.
Which offers some control of what is indexed and makes
the search go faster. Microsoft has their own idea of
what you want, which is why the interface on the thing
on the left is so annoying.

As well, at least for local disks, there is a tick box
to enable or disable indexing.

The Windows search tends to be a "federated search", meaning
data mining from local or remote storage is possible. And you
can search your individual email messages, just as easily
as the file content on a foreign volume. Perhaps this "Dropbox"
thing, has some mechanism for including a hook for
federated search.

Another mechanism, is Windows can have a CSC folder, containing
offline files. So even when a computer is not connected
to the Internet, the copies of files you've been working
on, are still available locally. Perhaps what you're seeing
are things in a cache and not directly on Dropbox ?

The CSC may be involved in things that "sync". And maybe
if you're not careful, the Indexing control panel may be
selecting to index what is inside CSC ?
