Dears, Hi, According to my requirement I need to change the default behavior of Solr for overwriting the whole document on unique-key duplication. I am going to change that the overwrite just part of document (some fields) and other parts of document (other fields) remain unchanged. First of all I need to know such changing in Solr behavior is possible? Second, I really appreciate if you can guide me through what class/classes should I consider for changing that? Best regards.
