bq. I assume the matches would work for the group.totalCount=GROUPED or UNGROUPED.
This will work in both of these cases in the latest patch in SOLR-2564. It will always log
the number of matches, not the number of groups.

> 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:
> {code}
> 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
> {code}
> 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...
