document scoring

Hello,

I am querying an index by using custom boost factors for each field. Usually
a query looks like:

fieldA:"term1"^0.2 fieldB:"term2"^4

when I get scores from HitCollector, they are not necessarily between 0 and
1.

How can I normalize these scores?

Best.

Try TopDocs. You can use getMaxScore and divide....
