Adding such a link directly in the user interface will require development. Theoretically it should be possible, since the internal object ID of the parent description is included in the URL of the browse page shown. I can't think of any easy way to add this without development, however. If you have developers in-house and want to try to implement something like this, let me know and I can see if our team has some suggestions on existing code you might be able to reuse.
In the meantime, using the back button on your browser should allow you to return to the parent description. Additionally, don't forget that if you click on any one of the results, you'll be able to use the treeview on the view page of the selected record to return to the parent description.
