Yes, it is possible to copy from a field to another field that has no value.
In fact, that is the only kind of copy you should be doing unless the field is multivalued. IOW, copy field is not “replace field”. -- Jack Krupansky From: Luís Portela Afonso Sent: Wednesday, August 07, 2013 7:22 PM To: solr-user@lucene.apache.org Subject: SOLR Copy field if no value on destination Hi, Is possible to copy a value of a field to another if the destination doesn't have value? An example: a.. Indexing an rss b.. The feed has the fields link and guid, but sometimes guid cannot be present in the feed c.. I have a field that i will copy values with the name finalLink Now i want to copy guid to finalLink, but if guid has not value i want to copy link. My question is, is that possible just with the schema, Processors, solrconfig.xml, and the data-config? Thanks a lot
