We are using Solr 4.0 (svn build 30th may, 2012) with Solr Cloud. While querying, we use field collpasing with ngroups set to true. However, there is a difference in the number of results got and the "ngroups" value returned.
Ex: http://localhost:8983/solr/select?q=messagebody:monit%20AND%20usergroupid:3&&group=true&group.field=id&facet.limit=20&group.ngroups=true The values returned are like <int name="matches">10</int> <int name="ngroups">9</int> Actual groups returned :4 Why do we have this discrepancy in the ngroups, matches and actual number of groups. Earlier we were using the same query with solr 3.5 (without solr cloud) and it was giving correct results. Any kind of help is appreciated. -- Regards, Nitesh Nandy
