Hello,
Is IndexSearcher ThreadSafe? I made a simple httpserver using grizzly as
described in
http://jlorenzen.blogspot.com/2007/06/using-grizzly-to-create-simple-http.html
which submit queries to a single instance of indexsearcher and I get some
errors (when I query with more then one threads) suc
Thanks for your answer,
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?
Best,

Take a look at org.apache.lucene.search.TopFieldDocCollector :
http://lucene.apache.org/java/2_3_0/api/org/apache/lucene/search/TopFieldDocCollector.html

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.

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
See IndexReader.getTermFreqVector() and various versions of that.
Also, search the archives for Term Vector, as you will find discussion
of it there. You may also, eventually, be interested in the new
TermVectorMapper capabilities in 2.3 which should help speed up the
processing of term ve
One correction, my valSrcScore was '0.7002756' not ''8.614598'. But,
again, it's not what I expected.

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...

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.

Ah I see, I need to cast it to TermPositionVector. OK.

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.
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.
I have implemented a Cu

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:
