Hi Check out the CollapsingQParser (https://cwiki.apache.org/confluence/display/solr/Collapse+and+Expand+Results). As long as you have a field that will be the same for all duplicates, you can “collapse” on that field. If you not have a “group id”, you can create one using e.g. an MD5 signature of the identical body text (https://cwiki.apache.org/confluence/display/solr/De-Duplication).
