Greg Miller commented on LUCENE-10258:
--------------------------------------
Hmm, after writing some test cases (and getting more coffee), I'm not sure what
I had in mind is possible. For this to work, the Scorable provided to
DoubleValuesSource#fromScorer() would need to already be wrapped with the
caching scorer. I'll leave this open for a little bit in case someone else sees
a way to do this that I'm not seeing, but I suspect I'll end up closing this
since I don't really see a path forward.

> DoubleValuesSource#fromScorer() is a helper method for wrapping a Scorable in
> a DoubleValues instance (providing the value of Scorable#score() as its
> value). It would be nice to leverage ScoreCachingWrappingScorer for this
> use-case to avoid unnecessarily recomputing the score if the Scorable is
> being used elsewhere.
