The simplest approach is probably to wrap your limiting query with this class: http://lucene.apache.org/java/2_2_0/api/org/apache/lucene/search/QueryWrapperFilter.html Then use that filter by calling an IndexSearcher.search() method that also takes a filter.

Re: Prioiritze new documents
Hy, a solution came into my mind: Every document gets boosted by a integer which I increment each time I add a new document to the index. So the newer documents should get a bigger boost than the older ones. I tried it out and ran into a problem: Although I set the Boost via doc.setBoost(value) for each document before writing it to the index it doesnt change anything. Even worse if I look at the index using Luke (Version 0.7.1) each document got a boost of 1 not of the value supplied. Who can help me?

From the Javadoc of getBoost(): Note: This value is not stored directly with the document in the index. Documents returned from IndexReader.document(int) and Hits.doc(int) may thus not have the same value present as when this document was indexed.

I already know this, but ALL documents got a bost of 1. The values should a least differ some how, shouldnt they?

Yes, it looks like a bug, at least in the javadoc. In FieldsReader, the
document is created but setBoost() is never called. So calling getBoost is
like calling get("field") on a field that isn't stored. Could you open an
issue for this?

Re: Prioiritze new documents
I think it is the case that Luke doesn't show the boosts, see http://www.gossamer-threads.com/lists/lucene/java-user/32020?search_string=Luke%20boost%201;#32020 On Dec 30, 2007, at 7:38 AM, Dominik Bruhn wrote: Hy, a solution came into my mind: Every document gets boosted by a integer which I increment each time I add a new document to the index.
