Subject Re: Find groups where at least one item matches a query
Date Wed, 08 Feb 2017 21:28:19 GMT
As per the documentation:
"So all downstream components (faceting, highlighting, etc...) will
work with the collapsed result set."

So, no, you cannot facet on expanded group. Partially because it is
not really fully expanded (there is a limit of items in each group).

But also, are trying to facet per group or globally? If globally,
maybe you can override the faceting query or have a custom component
(before facet one) that generates facet.query parameters based on what
you got back from collapsing.

If locally, maybe there is something in json.facet module to do nested
facet for each domain.

Or maybe it is worth running two queries, one for results and one for
facets.....

Regards,
   Alex.
