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
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:

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 *
Boosting during Indexing or boosting during search ?

{tags},{title},{summary},{contents}
Typically a phrase occurs too many times in contents as compared to the

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,
