Hi, I used solr 4.8 for indexing the web pages that come from nutch. I know that solr deduplication operation works on uniquekey field. So I set that to URL field. Everything is OK. except that I want after duplication detection solr try not to delete all fields of old document. I want some fields remain unchanged. For example assume I have a data field called "read" with Boolean value "true" for specific document. I want all fields of new document overwrites except the value of this field. Is that possible? How? Regards.
