> Let's look at an observation regarding "bucketSizeLimit" in facetStream; and 
> how we interpret it as a "limit". Suppose for 3 nested facets, 
> bucketSizeLimit = 10, we receive total 1000 rows. since bucketSizeLimit = 
> limit; ONLY the first top-level facet value's count will be returned; out of 
> 10*10*10, 1*1*10th rows will be fetched. And the behavior will be consistent 
> for any bucketSizeLimit we set,
> How about we have a separate parameter "limit" other than "bucketSizeLimit" 
> which can be set to any arbitrary number (though should be < 
> bucketSizeLimit^no_of_nested_facets), and that limit can be said "500". In 
> this way, we will have the true SQL limit feature in place in FacetStream.
