Hi Markus,
Tetra* will be parsed as a PrefixQuery, which returns a constant score
by default. You can enable scoring by calling
MultiTermQuery.setRewriteMethod(SCORING_BOOLEAN_REWRITE) on it[1].
However, this will have the downside that not all possible terms
matching this prefix will be considere
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
"Tet
What query did you run? Not all queries take index-time boosts into
account for scoring.

Hello
Downloaded & imported latest 5.2.1 version, but Index-scoring seems not to
work for me:
I index two types of documents:
- For one, I boost every field with a factor 1
- For the other one, I boost every field with 0.01
When I search, I get documents of both types, but for ALL document an
id
Hi Ravikumar,
You need to run a BooleanQuery with two clauses:
- a must clause that matches all parent documents
- a must_not clause that matches all parents that have children
Building this second clause can be done easily with a
ToParentBlockJoinQuery around a child query that matches all you
We have organised our segments in parent-child blocks and wish to
periodically delete parent-documents that don't have any children to
reclaim space via IndexWriter.deleteDocuments(Query)…
Is it possible to draft a Query that identifies such parents? Any help is
much appreciated…
