Why is it that you need to do that? I mean in practice one should
never keep more than a "sliding window + cache" in memory on the
client side. Fx. the 15 visible documents + 30 backwards and forwards
for fast scrolling.

Before you open that can of worms I think we need to figure what the
problem really is. Maybe it is with your angle of attack or maybe
Tracker's API needs a tweak... Could you describe your problem more
precisely?

Have you seen: http://live.gnome.org/MetadataOnRemovableDevices ?
