changes to import script to hopefully resolve Solr Java crashing

solr_import.sh

 
   #docker exec -ti --user=solr solr bash -c "cp -r /opt/solr/example/files/conf/* /var/solr/data/$core/conf/"
 
-  docker restart solr
+  #docker restart solr
 
   sleep 30
 
   docker run --rm -v "$directory/$location:/$core" --network=host solr:latest post -c $core /$core
 }
+
+Import_recursive()
+{
+  docker run --rm -v "$directory/$subdirectory:/$core" --network=host solr:latest post -c $core /$core
+}
