                 Key: JENA-164
                 URL: https://issues.apache.org/jira/browse/JENA-164
             Project: Jena
          Issue Type: New Feature
          Components: LARQ
            Reporter: Paolo Castagna
            Assignee: Paolo Castagna


LARQ used not to update the Lucene index as RDF statements were added/removed 
from a Jena Model.
LARQ is currently extending StatementListener [1] to keep a Lucene index in 
sync with a Jena Model, however this notification mechanism is not applicable 
in the case of SPARQL Update requests.

LARQ needs to update the Lucene index when a SPARQL Update request is received.
