Description

The "Testing Values" section of the Apache Jena "SPARQL Tutorial - Filters" page(http://jena.apache.org/tutorials/sparql_filters.html) does not produce the expected results. I made sure to pull the example files from the site to ensure the issue was not due to typos in transcription:

I then used the following query command:

$ sparql --data=vc-db-2.rdf --query=q-f2.rq
