Martijn van Groningen commented on LUCENE-3098:
-----------------------------------------------

That is true. It is just a simple un-orded collection of all values of the group field that have matches the query. I'll include this as well.

> When grouping currently you can get two counts:
> * Total hit count. Which counts all documents that matched the query.
> * Total grouped hit count. Which counts all documents that have been grouped in the top N groups.
> Since the end user gets groups in his search result instead of plain documents with grouping. The total number of groups as total count makes more sense in many situations.
