Is there any way (or workaround) to boost the scores for certain documents?
My problem is as follows:
The documents I am indexing may contain a number of literature references,
the more the better. Unfortunately the scoring algorithm ranks documents
with a lot of references in their body lower,
Hi Alex,
I just looked at this and had the following thought:
The RangeQuery must continue to iterate after the first match is found
in order to match everything within the specified range. In other
words, if you have a range of a to d, you can't stop with a, you
need to continue to d. At
Look on the contributions page (it's in the left navbar of the Lucene
site). There are some example of how to do this.
Just to note, the changes that are described in the text are done in
the nightly build of Lucene.

increase the number of potential matches or is there
something I'm missing.
Interesting that this topic just came up as I wanted to
I wouldn't bother downloading the WordNet - if planning to use only the
synonyms, get the Prolog file wn_s.pl where words follow the structure:
s(15303,1,'person',n,1,7229).
s(15303,2,'individual',n,1,51).
s(15303,3,'someone',n,1,17).
s(15303,4,'somebody',n,1,0).
when deleting by unindexed fields, you need to traverse the entire index,
and introspect each document:
IndexReader reader = IndexUtils.getIndexReader(index);
int max = reader.maxDoc();
for (int i = 0; i max; i++) {
if (!reader.isDeleted(i)) {
Document doc = reader.document(i);
if
