How to do facet group query on Apache solr

Question

I am doing a facet query on solr.. Which gives me facets and its count for each item... But now I want to perform a group query on facets.. Which gives me count according to group...

Example

Below is the data

Item1: Nike shoes (size:8,9,10) Item2 : Reebok Shoes(size:8,9,10)

Now in this case my brand facet query returns me result as below

• Nike:3

• Reebok:3

The result I required is

• Nike:1
• Reebok:1

Answer 1

have you enabled group.facet=true as explained here . You need at least 3.3
