Hi,

I have the following simplified product datamodel:

id, name, group_id, category_id

and I have a facet defined on the category that allows me to find out
the actual number of products within a category.

What I like to know is, how many distinct groups (-> group_id) I have
within a category. For example:

1, 'Product A', 'Group A', 'Category A'
2, 'Product B', 'Group A', 'Category A'
3, 'Product C', 'Group C', 'Category B'
4, 'Product D', 'Group D', 'Category B'

What I currently get is:

Category A (2)
Category B (2)

What I like to get is:

Category A (1)
Category B (2)

------

Is there a way to do this with thinkingsphinx and its facets support?

I looked at the sphinx docs and found the SetGroupDistinct function
(http://sphinxsearch.com/docs/manual-0.9.9.html#api-func-
setgroupdistinct) that seems to be a solution to my problem. Is there
a way to use it in thinkingsphinx?

Thanks for your help,

Andre
