looks like it has to be an arrayref but my understanding of the source
is not good enough to determine what has to go into the arrayref.
At least I managed to crash it with a naive
$args->{OUTPUTFACETS} = [ 'foo' => 2 ];

I found it very astonishing that Google showed no hit at all, except
from the SimpleServer source. Is this really so rarely used?
Perhaps because it is not documented? ;-)

Would really appreciate any hint
