-----------------------------
Hi Paolo/Andy,
I was searching for a solution regarding this. It is a very important feature
for our project. Would you please inform me when this can be implemented? Or is
there any work around that I can try?
Thanks

> 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
