REALM provides a Match History within a saved search. This helps you find any new matches for your saved search. Once the search is opened, you will see an option labeled Match History (this feature is not available when using the Map Layout).
When you click on this tab, you will have the option to View Matches From: Today, Yesterday, 2 Days, or Custom
The default is set as "Today" and provides any matches that have been found so far. You will also notice a column labeled Notified. This will let you know if a notification has been sent, scheduled, or if no notifications have been set up for the search.
Clicking on Custom provides a calendar with the days on which matches were found. The darker the blue, the more listing matches occurred that day. Hovering over the date will give the number of listings. Clicking on the day will load the listings.
