I'm implementing an equivalent of dbPedia lookup service  in
semantic_forms, leveraging on Lucene integration in TDB, and dbPedia mirror
with TDB  .
The dbPedia lookup service is really nice but:
- the hosted service is often down
- completion is in english only
A lookup service with TDB and Lucene would overcome these 2 problems.
So I would need completion with Lucene from SPARQL.
According to Jena doc., this does not seems to be implemented:
There are plenty of pages when searching for
>From these pages there is a code snippet here
but a regular Lucene API may exist.
