> If I have a rule to match pattern with Filter-RelSubset, VolcanoPlanner only matches 1 RelSubset in the RelSet, instead of all the subsets.
> {code:java}
>          if (operand.getMatchedClass() == RelSubset.class) {
>             // If the rule wants the whole subset, we just provide it
>             successors = ImmutableList.of(subset);  
>           } else {
>             successors = subset.getRelList();
>           }
