Description

We monitor the Solr logs to try to review queries that have hits=0. This enables us to improve relevancy since they are easy to find and review.

When using group=true, hits= does not show up:

2011-01-27 01:10:16,117 INFO  core.SolrCore  - [collection1] webapp= path=/select params={group=true&group.field=gender&group.field=id&q=*:*} status=0 QTime=15

The code in QueryComponent.java needs to add the matches() after calling grouping.execute() and add up the total.

It does return hits= in the log for mainResult, but not for standard grouping.

This should be easy to add since matches are defined...
