---------------------------------

MArtin,

Are you logging it in your latest patch?

If so, we can close this. We use the info in the log to try to find queries where users get 0 results, and we are using grouping exclusively.

> 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...
