Specifically, the pre-processing can be done with UpdateRequestProcessors: https://lucene.apache.org/solr/guide/7_2/update-request-processors.html
In your case, you probably want to chain *) CloneUpdate: http://www.solr-start.com/javadoc/solr-lucene/org/apache/solr/update/processor/CloneFieldUpdateProcessorFactory.html *) ConcatField: http://www.solr-start.com/javadoc/solr-lucene/org/apache/solr/update/processor/ConcatFieldUpdateProcessorFactory.html Note that ConcatField URP inherits FieldMutating URP, so you have some flexibility on how you define the fields: http://www.solr-start.com/javadoc/solr-lucene/org/apache/solr/update/processor/FieldMutatingUpdateProcessorFactory.html Set the target field to index-only (not stored) and it will only be used for search. The original fields can be set to be not-indexed, as David already explained. Regards, Alex.
