System.out.println("\n");

for(FacetResult result : example.runDrillSideways()) {
System.out.println(result);
}
}
The example doesn't new SimpleFacetsExample each time.
So in drill-down example, it indexes 2 times, the result number is 2 times.
in drill-sideways example. it indexes 3 times, the result number is 3 times.
Is it intended?
