Chris M. Hostetter commented on LUCENE-10534:
---------------------------------------------
Your two PRs seem good to me ... although PR840 should probably have it's own
Jira for tracking/CHANGES.txt purposes.
{quote}Most likely need a test case as well since the existing tests didn't
find any issue w/ the assumption.
{quote}
I don't see any new tests in either of your PRs ... did you forget to 'git add'
?

> MinFloatFunction
> (https://github.com/apache/lucene/blob/main/lucene/queries/src/java/org/apache/lucene/queries/function/valuesource/MinFloatFunction.java)
> and MaxFloatFunction
> (https://github.com/apache/lucene/blob/main/lucene/queries/src/java/org/apache/lucene/queries/function/valuesource/MaxFloatFunction.java)
> both check if values exist. This is needed since the underlying valuesource
> returns 0.0f as either a valid value or as a value when the document doesn't
> have a value.
> Even though this is changed to anyExists and short circuits in the case a
> value is found in any document, the worst case is that there is no value
> found and requires checking all the way through to the raw data. This is only
> needed when 0.0f is returned and need to determine if it is a valid value or
> the not found case.
