Thanks Adrien for the quick response - that's a good hint -
I simplified my code and realized, that the sorting DOES work, if I use
full words. With "*", index boosting is not taken into account - see below
my code, I used the two queries for testing:
"Tetrachloroethane" - scoring works fine
"Tetra*" - here, I get all the same scores.
I am building an auto-suggest, based on ontology terms. Scoring is crucial
there, and also, that I find parts of words.

Simplified test code:
public void simple(String inp) throws IOException
{
try
{
FSDirectory dir =
FSDirectory.open(FileSystems.getDefault().getPath(Co.folder()+"SEARCH\\ontoTest\\"));
analyzer = new EnglishAnalyzer();
IndexWriterConfig config = new
IndexWriterConfig(analyzer).setOpenMode(OpenMode.CREATE);
IndexWriter writer = new IndexWriter(dir, config);
index(writer, "4", "1,1,2,2-Tetrachloroethane", 1);
index(writer, "5", "Tetrachloroethane", 1);
index(writer, "6", "Tetrachloroethane", 10);
index(writer, "7", "Tetrachloroethane", 0.1f);
writer.close();
QueryParser parser; Query query;
parser=new QueryParser("TERM", analyzer);
query = parser.parse(inp);
IndexReader reader = DirectoryReader.open(dir);
IndexSearcher searcher = new IndexSearcher(reader);
ScoreDoc[] hits = searcher.search(query, 100).scoreDocs;
out("found: "+hits.length+" results!");
for(int i=0; i<hits.length; i++)
{
ScoreDoc sd=hits[i];
if(sd==null) continue;
int docId = sd.doc;
Document d = searcher.doc(docId);
if(d==null) continue;
out("<br>id: "+d.get("ID")+" - score: "+sd.score+" - "+d.get("TERM"));
}
}
catch(Exception e) {
e.printStackTrace();
}
}
public void index(IndexWriter writer, String id, String str, float boost)
throws IOException
{
Document doc=new Document();
FieldType ft=new FieldType();
ft.setIndexOptions(IndexOptions.DOCS_AND_FREQS_AND_POSITIONS);
ft.setStored(true);
ft.setTokenized(true);
Field f=new Field("TERM", str, ft);
f.setBoost(boost);
doc.add(f);
writer.updateDocument(new Term("ID", id), doc);
}
