Hi Solr Users, Can the LTR field value feature <https://solr.apache.org/docs/8_7_0/solr-ltr/org/apache/solr/ltr/feature/FieldValueFeature.html> be a vector field or a field with comma separated numeric values? Is it a supported feature? Instead of querying each field separately, which is adding up to the query cost, thinking if it is possible to put field values together in one field at index time and query that as a feature, thoughts?
Thanks, Rajani
