Subject [jira] [Created] (OAK-262) Query: support pseudo properties like jcr:score() and rep:excerpt()

Thomas Mueller created OAK-262:

             Summary: Query: support pseudo properties like jcr:score() and rep:excerpt()
                 Key: OAK-262
                 URL: https://issues.apache.org/jira/browse/OAK-262
             Project: Jackrabbit Oak
          Issue Type: Bug
            Reporter: Thomas Mueller

The query engine currently only supports properties that are stored within a node. It doesn't
currently support "pseudo-properties" that are provided by an index, for example jcr:score()
and rep:excerpt(). 

To support such properties, I suggest to change the Cursor interface to return an "IndexRow"
(a new class that can return such pseudo-properties as well as the path) instead of just the

This may also speed up queries that don't require to load the node itself (if access rights
can be checked efficiently or don't need to be checked for a given query).
