In theory, if you delete all documents at the Solr level, Lucene will delete all the segment files on the next commit, because they are empty. I have not confirmed with testing whether this actually happens.
It is far safer to use a new index as Erick has said, or to delete the index directories completely and restart Solr ... so you KNOW the index has nothing in it.
