> 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
path.
> 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).
