SOLR-18143: Upgrade the Lucene dependency from 10.3.2 to 10.4.0 (#4195)
Codec changes:
- SchemaCodecFactory, CuVSCodec, CuVSCodecFactory: Lucene103Codec ->
Lucene104Codec
- ScalarQuantizedDenseVectorField: migrated to
Lucene104HnswScalarQuantizedVectorsFormat;
confidenceInterval, compress, and dynamicConfidenceInterval
params are now deprecated; they're parsed but ignored with DeprecationLog
warnings
- BinaryQuantizedDenseVectorField: replaced
Lucene102HnswBinaryQuantizedVectorsFormat
with Lucene104HnswScalarQuantizedVectorsFormat using
ScalarEncoding.SINGLE_BIT_QUERY_NIBBLE
Documentation:
- Updated dense-vector-search.adoc to reflect deprecated scalar quantization
params
- Added Solr 10.1 section in major-changes-in-solr-10.adoc with codec change
downgradeability warning
- Added step in dev-docs/lucene-upgrade.md to document codec changes in
upgrade notes
Other:
- Removed test configs for no-longer-validated confidenceInterval/compress
constraints

> Issue Type: Improvement
> Reporter: Rahul Goswami
> Priority: Major
> Labels: pull-request-available
>
> Lucene 10.4 released last week and contains several important Vector search
> related changes. It also contains a critical enhancement which moves the
> MIN_SUPPORTED_VERSION (Version.LATEST-1) check to the segment level instead
> of requiring that the index be created in version no older than
> MIN_SUPPORTED_VERSION. This is necessary to be able to open the indexes
> originally created in Solr 8.x and upgraded via the recently introduced index
> upgrade capability (while on Solr 9.x).
