> The current {{getAllDims}} functionality is really the only way for users to determine the "top" dimensions in a faceting field (i.e., get the top dims by count along with their top-n children), but it has the unfortunate side-effect of resolving all child paths for every dim, even if the user doesn't intend to use those dims. For example, if a match set contains docs relating to 100 different dims (and various values under each), but the user only wants the top 10 dims with their top 5 children, they can call getAllDims(5) then just grab the first 10 results, but a lot of wasted work has been done for the other 90 dims.
> It would be nice to implement something like {{getTopDims(int numDims, int numChildren)}} that would only do the work necessary to resolve {{numDims}} dims instead of all dims.
