Stefan,
You have to load the data through "indexDataset" - I guess you are
loading it into a plain dataset in loadData.
The Lucene index is built as data is added to the dataset, not when the
dataset is wrapper later.

Thanks Rob,
The problem is, for someone like me, who is new in Jena, it’s hard to follow
the documentation – not enough examples and the explanations are kind of
ambiguous (again – from my point of view).
I was hoping on comment and snippet, specifically about my example.

What these lines are doing is creating a blank index, in particular the
last line simply associates a pre-existing index with a dataset i.e. It doesn’t
actually cause indexing to happen, typically you would first build a persistent
Lucene index using the command line tool
http://jena.apache.org/documentation/query/text-query.html#building-a-text-index
if you want to explicitly built the index from code your best bet is to
refer to the code for the commandline tool:
