Hi Joel
By group heads, is it referring to the document thatis use to represent
each group in the main result section?
Eg. Using the below 3 documentsandwe collapse on field supplier_id
supplier_id:S1
product_id:P1
supplier_id:S2
product_id:P2
supplier_id:S2
product_id:P3
With collapse on supplier_id, the result in the main sectionis as follows,
supplier_id:S1
product_id:P1
supplier_id:S2
product_id:P3
The group head of supplier_id:S1 is P1and supplier_id:S2 will be P3?
Facets (and even sort) are calculated on P1 and P3?

The CollapsingQParserPlugin currently doesn't calculate facets at all. It
simply collapses the document set. The facets are then calculated only on
the group heads.
Grouping has special faceting code built into it that supports the
group.facet functionality.

Hi
I read about "collapsingQParser returns the facet count the same as
group.truncate=true" and has this issue with the facet count and the after
filter facet count notthe same.
Using group.facetdoes not has this issue but it's performance is very
badcompared to collapsingQParser.
I trying to understand why collapsingQParser behave this way and will need
to explain to management.
Can someone explain how collapsingQParser calculatethefacet countscompated
to group.facet?
Thank you,
Derek
