How to search for documents that do not contain a word in a section?

Question

For example: (deleted% within folder) finds all documents that have deleted in the folder
I want to find all documents that do not contain "deleted%" within folder.

Answer 1

If you have other criteria, then you can use "other criteria NOT deleted% within folder". However, if there is no other criteria, then you cannot just begin with NOT, so you have to use "% NOT deleted% within folder", but on a large data set that will result in an error about the wildcard expanding to too many terms.
