Hi, I would create a search alias, that contains the latest versions of the different collections.
See: https://lucene.apache.org/solr/guide/7_3/collections-api.html#collections-api Then you use this alias to search for results You get better results if you define the same schema for all collections Best Regards Peter Gylling Jørgensen Findability Consultant Mail: peter.jorgen...@findwise.com<mailto:peter.jorgen...@findwise.com> Mobile: +45 42442890 Den 26. jun. 2018 kl. 13.55 skrev angeladdati <angeladd...@gmail.com<mailto:angeladd...@gmail.com>>: Hi: I have two sources to indexing: Database: MetadataDB1, MetadataDB2, File Url...

When I search, I need search and show the merge result: Database + Files (MetadataDb1, MetadataDB2, MetadataF1, MetadataF2, File Url, Contain, ...). Is it possible? Regards!
