Fuseki + Larq : Lucene indexing

[Jérôme]

Hi,

i'm trying to use LARQ with my Fuseki server.
I would like to programmaticaly indexing(with lucene) documents when the 
server starts.

Something like that:

Model model = ModelFactory.createDefaultModel();
IndexBuilderString larqBuilder = new IndexBuilderString();
model.register(larqBuilder);
FileManager.get().readModel(model, "Data/books.ttl");
larqBuilder.closeWriter();
model.unregister(larqBuilder);
index = larqBuilder.getIndex();
LARQ.setDefaultIndex(index);

Is it possible? In which class it would be the best?

Thanks

Jerome
