------------------------------------------

HI,
I'm also interested in this thread.
For my purpose, it's sufficient to sort facet after  compute the top-n facets by weigth
(as suggest by  Shai Erera)

Thank in advance for any suggestion.

> Facet support sorting through {{FacetRequest.SortOrder}}. This is used in the {{ResultSortUtils}}.
For my application it would be very nice if the facets can also be sorted on their label.

> I think this could be accomplished by altering {{FacetRequest}} with an extra enum {{SortType}},
and two extra {{Heap}}  in {{ResultSortUtils}} which instead of comparing the double value,
compare the CategoryPath.
> What do you think of this idea? Or could the same behaviour be accomplished in a different
way already?
> (btw: I tried building this patch on the trunk of lucene5.0; but I couldn't get the maven
build to build correctly. I will try again lateron on the 4.6 branch.
