Hi
@Peter This is actually the requirement. We have. For both sort options (index,
count) we would like to have the possibility to add the desc option.
Instead of this result
q=*:*&facet=true&facet.field=image_text&facet.sort=index&rows=0
<lst name="facet_fields">
<lst name="image_text">
<int name="a">12</int>
<int name="b">23</int>
<int name="c">200/int>
</lst>
</lst>
We would like to add desc to the sort option like facet.sort=index,desc to get
the following result
<lst name="facet_fields">
<lst name="image_text">
<int name="c">200</int>
<int name="b">23</int>
<int name="a">12/int>
</lst>
</lst>

Betreff: Re: Facet sort descending
Hi,
This question could possibly be about rare idr facet counting - i.e. retrun the
facets counts with the least values.
I remember doing a patch for this years ago, but then it broke when some
UninvertedField facet optimization came in around ~3.5 time.
It's a neat idea though to have an option to show the 'rarest N' facets not
just the 'top N'.
Thanks,
Peter
