Hello Users,
I am using solr version 7.4.0. I have around 10 collections which are created using the default solrconfig.xml. Few collections have the column : *solr_created_dttm* which is indexed. I want to delete all the documents from these collections which are older than 6 months. I understand there is *DocExpirationUpdateProcessorFactory *which needs to be added to solrconfig.xml. Can someone please help with the configuration I need to add. I tried a few things like adding expiration filed but wanst sure how to calculate expiration period to check *solr_created_dttm*is 6 month older? Also since all the collections share the same config file this processor won't affect those collections which don't have " *solr_created_dttm* " . Please confirm if my understanding is correct as I only want to delete documents from collection having filed "*solr_created_dttm* " Thanks in advance !! Regards, Amruta
