> 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.
