> Add minimum group count for Field Collapsing
> --------------------------------------------
>
> Key: SOLR-3152
> URL: https://issues.apache.org/jira/browse/SOLR-3152
> Project: Solr
> Issue Type: New Feature
> Components: search
> Reporter: Kellen Dye
> Priority: Minor
> Labels: collapse, grouping
>
> When performing field collapsing, it is occasionally desirable to filter out
> groups which have fewer than a given number of matches. So, for example:
> q=solr+memory&group=true&group.field=manu_exact&group.min=3
> would group on 'manu_exact', but exclude groups where numFound is less than 3.
