We can remove it - it's easy enough to add back if we never do need it. -Yonik http://lucenerevolution.org Lucene/Solr Conference, Boston Oct 7-8
Re: matches in result grouping
Correct. The "matches" is the doc count before any grouping (and for field.query that means before the restriction given by field.query is applied). It won't always be the same though - for example we might implement filter excludes like we do with faceting, etc. -Yonik http://lucenerevolution.org Lucene/Solr Conference, Boston Oct 7-8 Thanks Yonik for the explanation. One more question. I think SearchGroupDocs.matches is unused (I think TopDocsCollector.totalHits is used for displaying numFound in each group). Will it be used in the future for some reasons (if so it should be referenced for displaying numFound) or can we remove it? Thanks, Koji -- http://www.rondhuit.com/en/

Can anyone explain it? Probably multiple GroupCollectors are generated for each group.field, group.func and group.query and match can be counted per collector. Koji -- http://www.rondhuit.com/en/
