You could have a timestamped field that is auto-set to the time of indexing the document: <field name="index_time" type="date" default="NOW" /> where date is a solr.DatePointField. There is a warning in the API about doing that in SolrCloud, so use with care or use the TimestampUpdateProcessorFactory that is mentioned: http://lucene.apache.org/solr/7_2_1/solr-core/org/apache/solr/schema/DatePointField.html - Toke Eskildsen
