"Negative Boost" removed from Solr 8.4
Hi fellow users,
I am not able to locate any JIRA for removal of "Using Negative Boost" in
Solr 8.4, nor any discussion around the same. I will be grateful if someone
points me to the right direction to any conversation around it such that we
understand the motivation and work around in our project.

The take away is that greater than zero and less than 1 values, such as
0.1, will down boost a document.

Scorer must produce positive scores (LUCENE-7996
<https://issues.apache.org/jira/browse/LUCENE-7996>)
Scorers are no longer allowed to produce negative scores. If you have
custom query implementations, you should make sure their score formula may
never produce negative scores.
As a side-effect of this change, negative boosts are now rejected and
FunctionScoreQuery maps negative values to 0.

Hello Amrit,
Can you mention how you are giving a negative boost?
I have a working example:
