Hi Emir, Thanks for the tip about DefaultValueUpdateProcessorFactory. But even though I agree that it most likely isn't too hard to write custom code that does this, the overhead is a bit too much I think considering we now use a vanilla Solr with no custom code deployed. So we would need to setup a new project, and a new deployment procedure, and that is a bit overkill considering that this is a feature that would help me as a developer and administrator only a little bit (ie nice-to-have), and at the same time would not have any impact for any end user (except, possibly negative side effects because of bugs etc).

Hi Jimi, I don’t think that you can do it using schema, but you could do it using custom update request processor chain. I quickly scanned to see if there is such processor and could not find one. The closest one is https://lucene.apache.org/solr/6_6_0//solr-core/org/apache/solr/update/processor/DefaultValueUpdateProcessorFactory.html <https://lucene.apache.org/solr/6_6_0//solr-core/org/apache/solr/update/processor/DefaultValueUpdateProcessorFactory.html> It should not be too hard to adjust it to do what you need.
