Lucene Field score value
Hey guys,
I was wondering if there is a way to retrieve score of a field in a document
?
If my document looks like this:
{itemID},{field 1},{field 2}
I'd like to get score of individual fields 1 and 2 rather than the score of
the entire document.
Is it possible ?
thanks,
AZ

Hi,
Does anyone know how to retrieve the score of an individual field instead of
doing:
hits = score(i); This will get me the entire score of the document. I'd like
to get the score of a single field by specifying the field name.
thanks,
AZ

Though I am not sure what is the possible use case for thing like below, but
here is the pointer:
Using IndexSearcher you can get the "Explanation" for the given query and
document-id. Complex Explanation has multiple sub-explanations and so forth.
Simple Explanation would contain the weight of the query (queryWeight) and
weight of the field (fieldWeight).
You can simply write some method which consumes Explanation and returns you
the score for given field. Note that, there might be explanations for the
same field - so you need to add them. Don't forget to multiply by factors
like boost-factor to get the exact score for a given field.
Thanks, Shailendra

You can boost any clause of a query:

title:foo^5 header:foo^2 body:foo

Re: Lucene Field score value
Posted by Askar Zaidi <as...@gmail.com>.
I'll have to use StringBuffer and get the Explanation in it as a String.
Then parse StringBuffer to get the scores of each field, then add them and
then boost the scores. That seems to be a non-trivial task. Is there any
other way around it ?
Considering Boosting, can I boost the score of a field ? I came across
Boosting of a term in the query so that would mean,
"apache^4 jakarta"
This means I am more keen to find apache than jakarta. I am keen to boost
the score of a field, how can that be done ?

Re: Lucene Field score value
Posted by Askar Zaidi <as...@gmail.com>.
Using the Explanation method can help me get the exact score of a field. I
am concerned with how I can access it , this is what I am doing:
for(int i=0;i<hitCount;i++){
doc = hits.doc(i);
score = hits.score(i);
int ID = hits.id(i);
System.out.println( id + "\t" + score + "\t" + doc.get
("item"));
Explanation exp = searcher.explain( query , ID );
System.out.println( exp.toString() );
}
This shows me o/p as follows (trimmed output):
6.6197186E-4 = (MATCH) product of:
0.0033098592 = (MATCH) sum of:
0.0033098592 = (MATCH) weight(contents:innovation in 4), product of:
0.28244132 = queryWeight(contents:innovation), product of:
1.0 = idf(docFreq=5)
0.28244132 = queryNorm
0.01171875 = (MATCH) fieldWeight(contents:innovation in 4), product
of:
1.0 = tf(termFreq(contents:innovation)=1)
1.0 = idf(docFreq=5)
0.01171875 = fieldNorm(field=contents, doc=4)
0.2 = coord(1/5)
The 6.6197E-4 is the total score of the document. How can I access the
fieldWeight ? Any example would be great.

Boost the other three fields at search time. Boosting during
index time expresses "this document's title is worth more than
other doucments' titles". Boosting during search time expresses
"I care about matches on this clause more than I do on other
clauses".
Will it help? How should I know? It's *your* application and
*you* are the one who is dissatisfied with the current scoring <G>.
All I can say is try it and find out. You might consider using Luke
to try various boosts without having to mess with too much code.

Re: Lucene Field score value
Posted by Askar Zaidi <as...@gmail.com>.
Boosting during Indexing or boosting during search ?
I have 4 fields:
{tags},{title},{summary},{contents}
Typically a phrase occurs too many times in contents as compared to the
other fields. If I get the score of contents field , I can pass it through
an adjuster function which will bring the score down. Something like:
public static double adjuster(double count){
double newCount;
newCount = 1/Math.exp(count);
System.out.println(newCount);
return newCount;
}
Do you mean I could boost the values of the other 3 fields ? Will that help
? Would there be a way to bring down the score of the contents field ?
thanks,
AZ

Wouldn't boosting handle this for you?

To be more specific:
I want to retrieve the scores of individual fields inside a document so that
I can manipulate the score of one field. This is the requirement of my
application. After the manipulation I can add these scores and then show the
total.
