Let me ask the next question in another thread,
and it is:
how to find out each score contribution from a booleanquery.
Best regards

This should be very straight forward usage but i am not getting any
usefeul info from explain:
Explanation expl = is.explain(booleanQuery.build(), 10);
System.out.println(expl);
This prints:
0.0 = Failure to meet condition(s) of required/prohibited clause(s)
0.0 = no match on required clause
Yes, i know that feature but so far it did not help me much but
i am still looking into that.
Thanks

Hi,-
i really want to know why the scoring works this way: search String is
either MAINO or MAINS: MAIN appears as the 276th entry in the results.
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 0 th result
NEW HAMPSHI

Hi,
The defaulting scoring in Lucene uses tf x idf^2 instead of tf x idf .
Does any have have insight that why not using tf x idf?
Here is the note on score calculation.

Hello,
I am using treceval for precision, recall calculation. Treceval takes
Relevance judgments and Result file as an arguments to calculate the
precision, recall. There is a similarity parameter in the result file.
The score which is calculated by Lucene is equal to that similarity
