> Lucene 10.3 added a
> [LateInteractionField.|https://lucene.apache.org/core/10_3_1/core/org/apache/lucene/document/LateInteractionField.html].
> Basic support for this in Solr would be a new {{FieldType}} and some
> associated {{QParser}} support to be able to use tose fields in conjunction
> iwth Lucene's {{TestRescoreTopNQuery}} and/or {{LateInteractionRescorer}}
> (and/or {{LateInteractionFloatValuesSource}} + {{DoubleValuesSourceRescorer}}
> -- see SOLR-17951)
> BUT! ... the most complex part of figuring out ow to support
> {{LateInteractionField}} in Solr is going to come down to what the field
> values should look like when adding/updating docs containing this field --
> and what the query input should look like -- given that the field values are
> "multi-dimensional array of floats"
