Described herein is a system that enables a user to filter notable events, representations for which are presented on an interactive timeline associated with a teleconference session or a collaboration environment. The filtering can be implemented based on a type of a notable event and/or based on a specific notable event. The system is also configured to enable a user to search for instances of a type of event and instances of a specific notable event. The system is configured to provide results to the search request that list the teleconference sessions that include the located instances. The user can then select a teleconference session from the results to view an interactive timeline that includes representations of the located instances. Consequently, the system provides a tool that enables a user to efficiently and effectively locate events on an interactive timeline that are desirable (e.g., activity the user wants to view).
