This query returns 2 groups first group has 1 document and second group has 2 documents.

Use group.ngroups=true to include the number of groups in the response.

Documentation -
group.ngroups - true/false
If true, includes the number of groups that have matched the query. Default is false.

One comment to above answer that is 100% correct however there is extra condition!

You can not have:

group.main => 'true'

Any other alternative solution to get group count when using group.main=true? – Gowthaman Oct 13 '16 at 15:15
This is what I did to get group count but at the same time using `group.main=true`. I made 2 calls to solr. The first call will have `group.ngroups=true&rows=0`. This way we don't get any data but only the count. The second call will have `group.main=true'. Hope this helps someone. – Gowthaman Oct 13 '16 at 17:06
