(something like the final lucene score should be interpolation of uni-gram
score, bi-gram score, tri-gram score,... and so on)
Any help is much appreciated.
Thanks

Hi,
I am trying to find the actual lucene score of the document after the search. I
have set different boost values to fields. I am using document.getBoost(), to
find the score but I am getting document boost as 1 for all the documents.
Is there any way I can calculate the actual score of the
Hi,
I search using the ComplexPhraseQueryParser (e.g. "great* sum*"), it becomes
SpanNearQuery so i cannot use multiTermQuery.setRewriteMethod(). Because prefix
query is constant query, it can only sort the document by the order of reading
files.
Which method should I use to change it? And

The answer tends to vary based on exactly what type of query you are

Document boost is distributed to each field when creating the index.
It is not stored anywhere. So it's not in the equation to calculate score.

Is the docboost being used in scoring currently? I haven't been able
to see a clear connection between it and the score that lucene
calculates both empirically and in the scoring code itself.

It's in the Javadoc for Similarity class.
You can use that along with Explanation (class) to get a good picture
of what's going on with scoring.

I know there used to be a webpage that gave the algorithm used by Lucene
for scoring, along with some info on what each variable controlled, to
some extent... I was looking to brush up on what the idf controls (and
what will happen if I override it) but I can't seem to find that page
any longer
Hi
Does lucene relevancy score depend on the total number of documents in
the index? Will I get different scores for the same document for the
same query for indexes of different sizes? If it does, when does it
return a higher score?
Thanks in advance,
Ravi.
