+
+Whether the [Collapsing query parser](https://cwiki.apache.org/confluence/display/solr/Collapse+and+Expand+Results) should
+be used when searching in order to collapse nodes that are descendants of 'jcr:content' nodes into the 'jcr:content' node only.
+E.g. if normal query results would include '/a/jcr:content' and '/a/jcr:content/b/', with this option enabled only 
+'/a/jcr:content' would be returned by Solr using the Collapsing query parser.
+This feature requires an additional field to be indexed, therefore if this is turned on, reindexing should be triggered
+in order to make it work properly.
