Gus Heck commented on SOLR-8109:
--------------------------------
Sometimes when using dynamic fields, the majority of the dynamic fields
generated by the input data are single valued but a few annoying fields happen
to be multivalued. This forces the dynamic field to be multivalued, which
precludes sorting on all fields originating from the dynamic field. At present
this can only be handled by having an ingestion pipeline (or other
preprocessing code) anticipate the dynamic configuration and add a second field
for sorting. This creates a need for the ingestion to model (and duplicate) the
dynamic field configuration. Although not always appropriate, the most basic
thing such processing can do is pick the first value for the "sort" field, and
ignore the rest. The patch I am attaching adds a firstValueOnly attribute to
copyField in the solr schema, which provides this first basic workaround
without an ingestion pipeline.
