hossman opened a new issue, #15328: URL: https://github.com/apache/lucene/issues/15328
### Description `VectorSimilarityFunction` (and it's concrete subclasses) are the only `ValueSource` impls (AFAICT) that produce `FunctionValues` impls which _**do**_ override `floatVal(doc)` but do **NOT** override `doubleVal(doc)` -- so they inherits the default impl from the `FunctionValues` abstract class, throwing `UnsupportedOperationException` Practically speaking this means `VectorSimilarityFunction` subclasses are the only `ValueSource` impls (AFAICT) that _**can**_ be used in a `FunctionQuery`, but can **NOT** be used in a `FunctionScoreQuery` because `ValueSource.asDoubleValuesSource()` delegates to the `doubleVal(doc)` ### Version and environment details Affects main, and all previous versions of Lucene that contain `VectorSimilarityFunction` Fix (with tests) is fairly straight forward: [lucene.bug.VectorSimilarityFunction.doubleVal.patch.txt](https://github.com/user-attachments/files/22858305/lucene.bug.VectorSimilarityFunction.doubleVal.patch.txt) -- This is an automated message from the Apache Git Service.
