Solr does not delete files/documents by itself with the exception of TTL (Time To Live, since Solr 4.8. See: https://lucidworks.com/2014/05/07/document-expiration/).
so unless you've configured TTL, which I doubt you have if you're asking this question then I'd suspect several possibilities: > You have DIH set to clean every time it's run and it didn't run successfully. > So the clean step (which deletes all docs) finished but the index didn't get > repopulated. > Someone issued a delete-by-query on *:* > Someone just deleted the index files from your sever accidentally.
