I'm trying to create a simple search via Search Syntax or the Advanced Search option in the thick client that will identify documents that have been truly changed vs. documents that have not. I understand you can use the date option in a customized search to see when a document was created or modified...if the dates and time are the same, it was never modified as the modified time also reflects the creation time of the document. I'm trying to locate the documents where the modified and creation dates and times do not match. I have tried the various combinations of the search operators to no avail.  Maybe I'm going loony while working from home and not having contact with adults over the age of 30 but can someone please assist me.
