How do I search for files which are not linked to Moodle?

I am conducting house keeping on our Alfresco site and need to find which documents are not linked to Moodle and haven't been modified in over 6 months. I think the latter will be simple enough by sorting the search results, however I am struggling to locate the linked documents.

So I managed to figure it out, I think. If you search the repositories with the search term -Tags, it brings back everything that isnt tagged. My next quest is to find if the In Moodle tag is added automatically or if it has to be added manually.
