Hi Jerome,
it is currently not possible to retrieve positions via LARQ.
I do not even know how to imagine doing this (syntactically) in
a SPARQL query, but if you or someone else have an idea on how
this might be possible we can discuss it.

One way to do it could be to use LARQ to perform a first search,
then retrieve the literal value and use Lucene, independently from
Jena, to perform the highlighting you want.
What do you think about this approach?
It's not ideal, I know... but it should be possible and easy.
