Hello Forum,
I've had a search in the mail archives and on the 'net, but I'm sure I wouldn't
be the first to have a requirement for this:
Does anyone know of a good way to perform a reverse-sorted facet query (i.e.
rarest first)?
As you know facet.sort toggles between sorting on count or field name, but
there's no built-in method for reverse count.
One way I've found to do this is to set facet.limit=-1 (and facet.mincount) to
get the entire list, then take 'bottom-5' to get a 'rare' list.
This works, but it's not great for very large lists.
Does anyone know of a better way?
Many thanks,
Peter
