Hi All, I recently switch from solr field collapse/expand to grouping for collapse search result All seem good but CPU is always high (80-100%) when i set param group.ngroups=true.
We set ngroups=true to get number of groups so that we can paginate search result correctly. Due to CPU issue we need to turn it off. Is ngroups=true is expensive feature? Is there any way to prevent CPU issue and still have correct pagination. Thanks, Tien
