Hi All,
We are having an index with the fields, HEADING and WRITER.
HEADING is having the high boost factor and WRITER is having a low boost.
Let the data is as follows:
HEADING WRITER

Cool, that worked, sort of.
The customScore method that is overridden from CustomScoreQuery has a
signature of:
public float customScore(final int doc, final float subQueryScore,
final float valSrcScore);
The javadoc states that the valSrcScore is the value from the field of
my ValueSourceQuery.
Hi,
In the constructor for your DomainCustomScoreQuery try calling
setStrict(true);
after invoking the superclass ctor. I think that will fix the problem you're
seeing.

One correction, my valSrcScore was '0.7002756' not ''8.614598'. But,
again, it's not what I expected.

I am trying to 'muck' with document scores from Lucene. I have
certain business rules where I have a field named 'domainScore' within
my index. The 'domainScore' value is a float. What I want to do is
add this value to the document sub query score from the Lucene search.

The IndexSearcher is thread-safe. The QueryParser is *not*. From the
JavaDocs for QueryParser
Note that QueryParser is *not* thread-safe.
So I'd guess you're using a single QueryParser across multiple
threads. Just use a new one each time, they're not expensive...

See IndexReader.getTermFreqVector() and various versions of that.

Sorry, this was a bit nonsense ;)
I store a document with a content field like this:
Document#add(new Field("content", someReader, TermVector.WITH_OFFSETS));
Later I search this document with an IndexSearcher and want the
TermPositions from this single document.
There is a IndexReader#termPosit
Take a look at org.apache.lucene.search.TopFieldDocCollector :

Hi,
how do I get the TermVector from a document which I have gotten from an
IndexSearcher via IndexSearcher#search(Query q).
Luke can do it, but I do not know how...
Thank you.

I will look into this in more detail.

Hello,
How can I use a hit collector and sort object in query? I looked at the API
and sort is only usable with hits. Is it even possible? since hitcollector
returns a bitset - how do we do the ordering?
