Not a dev, so apologies if this is a dumb question, but are Saved Searches used as a parameter in a Map/Reduce required to be Public? I ask because I'm testing out the Techfino Mass Delete bundle and it works great, but I'm not crazy about having the search it's pulling from be public. Not that we have any users who could fire off the script, but I still don't have a high comfort level with non-Admins being able to see this search. I dug through the code a bit as well as that parameter and couldn't see any setting that was requiring the search to be public.

its a requirement on the field used to store the saved search

Interesting. That's disappointing, but I appreciate the answer @battk.
