Active Search
An active search is a search you set to run automatically at regular intervals. It captures any entity that's added or changed since the time the last search was run.
You can use active searching to specify the attributes of an entity you want to monitor but not search for manually on a regular basis.
You can set up an active search for any type of entity and use it with other types of searches – Like standard, attribute, advanced, thesaurus, or scope searches.
If an entity that matches your search criteria is added or changed, you'll see a notification about it in the Alerts section of the Navigator.
