The quickest way to locate new matches for a saved search once you have been notified by email or through app notifications is to log into REALM and view your Recent Activity Panel .
Locate the notification for the new matches in the search (the Recent Activity is in chronological order).
Under the notification you will see a link that says Show Listing(s).
Click the link to show all the new matches available at that time.
Click the listing of interest to open. Please note that the recent activity menu can be closed by clicking the "X" at the top right corner of the panel.
Alternatively, you can open the saved search by clicking on the search name and use the Sort button to view by Days on Market or Last Update.
