How are you using the score? The fact that you want them back to the
old way implies to me that you are using them for something other than
for sorting the results.

: To get the normalized scores use:
...
: float score = hits[1].score / td.getMaxScore();
Strictly speaking, this code will not return the exact same scores as the
deprecated Hits API. the Hits class only normalizes the scores if the max
score is greater then 1.0f
(yet another one of
/ td.getMaxScore();

HitCollector scores are not normalized to the 0-1 range, they
are "raw". You have to get the maximum score returned and
normalize the raw scores. See TopDocs.getMaxScore
as I remember.

Hello,
I have project which I am trying to switch from lucene 2.3.2 to 2.4 I am
getting some strange scores
Before my code was:
Hits hits= searcher.search(query);
Float score = hits.score(1)
and scores from hist was from 0-1; 1 was 100% match
I change code to use hit collector
