Subject [jira] [Created] (OAK-3147) Make it possible to collapse results under jcr:content nodes

Tommaso Teofili created OAK-3147:
------------------------------------

             Summary: Make it possible to collapse results under jcr:content nodes
                 Key: OAK-3147
                 URL: https://issues.apache.org/jira/browse/OAK-3147
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: solr
            Reporter: Tommaso Teofili
            Assignee: Tommaso Teofili
             Fix For: 1.2.4, 1.3.4, 1.0.18


In some use cases a lot of search results live in descendants of jcr:content nodes although
the caller is only interested in those jcr:content nodes as results (that post filtering being
applied using primary types or other constraints) so that the Solr query could be optimized
by applying Solr's Collapse query parser in order to collapse such documents and therefore
allowing huge improvements in performance, especially on the query engine not having to filter
e.g. 90% of the nodes returned by the index.
