Search +QueryParser+Score
Hey Guy's
Apologies.....
I have a Question
Is there any API avaliable in Lucene1.4 to set the "Score value to 1.0f or
lesser "
BEFORE doing the Query Parser for search , so that the returns Hits for
the Score settings only.
with regards
Karthik

I don't really understand what QueryParser has to do with your
question. If you want only Hits that have a score of 1.0 (keep in mind
that Hits normalizes scores if they are over 1.0), why not just walk
all the Hits in order until you get to one that is not 1.0?
Or, use a HitCollector to collect hits (scores not normalized with a
HitCollector) and bail out when you are done. (although bailing out of
a HitCollector is not as clean as we should make it in Lucene 2.0 - we
should add that to the whiteboard).

Kathik,
I have a really hard time following your questions, otherwise I'd chime
in on them more often. Your meaning is not often clear.
In the case of normalizing the score to 1.0 or less - this is precisely
what Hits does for you. I'm not sure what you mean by "BEFORE" doing
QueryParser - a score is computed based on a query, so it necessarily
must come after.

Kathik,
I have a really hard time following your questions, otherwise I'd chime
in on them more often. Your meaning is not often clear.
In the case of normalizing the score to 1.0 or less - this is precisely
what Hits does for you. I'm not sure what you mean by "BEFORE" doing
