Hi Andy, thanks for the quick response, which makes quite clear what was wrong: A before for Joseki, I used a pre-built read-only tdb database.
Well, so I have to use Fuseki for tdb building as well. I'll check and report back.

However, this did not work for me. Joachim, Fuseki indexes the data as it's loaded, it does not index existing data on startup. I see what you see in the Lucene directory before data is loaded. How is the data being loaded into the store? Have you tried the config-tdb-text.ttl example? I have just checked using that, and also modified to add something more like the entity map you have and it works for me. I've tried s-put and the web UI (SPARQL update) to load data into the current snapshot build and text queries returned something. If you have a complete, minimal example of load-query lifecycle that would be most useful.
