when using group=true facet numbers are "incorrect"
Hi,
I've noticed that when field collapsing and faceting are both used in the
one query the facet numbers ignore the grouping. In my example I have three
documents (I have a small index for testing) and if I group on a certain
field I get two groups in the results but the facet numbers show that there
were three hits.
I understand that's a valid thing for faceting to do, I was just wondering
if there's any way to get it to do the faceting on the groups returned.
Otherwise I guess I'll need to convince the UI people to just show the
facets without the numbers.
Cheers,
Greg

How to go about if you want to get the number of groups?

We don't have true "post group faceting" currently (i.e. where the
units for facet counts would be numbers of groups, not numbers of
documents).
group.truncate just truncates the list of documents in each group, and
faceting still returns numbers of documents, not numbers of groups.
This is why I advocated the name group.truncate instead of
group.after, and have avoided any mention of "post grouping" on the
wiki page.

what you are asking about is generally refered to as "post-group faceting"
and can be activated using "group.truncate"...
