When I got it right, Fuseki is supposed to build the text index when it starts

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.

Starting fuseki (jena-fuseki-0.2.8-20130618.075236-28-server.jar) with an empty
index directory, for a very short time, it looks like this:
-rw-r--r--. 1 root root 45 Jun 20 13:46 segments_1
-rw-r--r--. 1 root root 0 Jun 20 13:46 write.lock
and then it stays like this:
-rw-r--r--. 1 root root 45 Jun 20 13:46 segments_1
-rw-r--r--. 1 root root 20 Jun 20 13:46 segments.gen
Text queries yield an empty result, while standard sparql queries work.
I can't figure out what could be wrong with my config:
## ---------------------------------------------------------------
## Read-only TDB dataset (only read services enabled).
<#service_stw_combined> rdf:type fuseki:Service ;

# skos:altLabel
[ text:field "text" ; text:predicate skos:altLabel ]
# skos:hiddenLabel
[ text:field "text" ; text:predicate skos:hiddenLabel ]
) .
Help would be much appreciated.
Cheers, Joachim
