How to search for records where a field doesn't exist
If this has been answered in another thread, please link it here. It could be described in different ways by different people and I was not able to think of any unique keywords or phrases that would return relevant answers from the forums.
Does anyone know how to pull up records in a search based on a field not existing? I would like to have a saved search that contains journal citations that don't have a PDF. When I search with "Attachment File Type" is not "PDF", it pulls up everything with at least one attachment that isn't a PDF, which is pretty much everything.
