An expression that allows, at query processing time, use of index-based access to the the (underlying) relational tables, instead of simply retrieving the table rows first and then applying a filter. This property is useful for retrieval based on conditions involving subject, predicate, or object generated from logical table column(s) and involves some transformation.
