I don't think so. The main problem is that we are retrieving each facet at a
time. This gets really better when we retrieve all facets at once. The problem
is that if you ask for a setSpec containing all facets, and one is empty, then
the result is empty. I've tried to patch zebra for that, but didn't finish it.
The IndexData guys didn't seem to accept such a solution anyway.

The best approach IMO is to make rebuild_zebra.pl create phantom entries for
all facets. But didn't have the time and memory to do it.

PS: When we first tried zebra facets in Reno, they were really better
speed-wise. I think something changed between 2.0.47 and 2.0.60 that made them
worse.
