filtering the search to the day, so today, 2 days ago, 3 days ago

Once one SOX auditor wanted systemnotes search for whole year. No I ran the search by grouping like you , took me about a week to gather all the data. I saved all the search extracts to a onedrive folder and shared the folder to auditor - all 25 GB of CSV files for him to audit LOL😂

This may be something you want to script with a saved search task
