# Configure Event Storage

You can configure how document tracking stores the events by modifying the `[DocumentTracking]` configuration in your components. By default, document tracking stores all events, but you can use the `PositiveEventFilter` and `NegativeEventFilter` configuration parameters to reduce the number of events to store.

- `PositiveEventFilter` allows you to configure a list of events that you explicitly want to store.

- `NegativeEventFilter` allows you to configure a list of events that you do not want to store.

If you configure both parameters, `PositiveEventFilter` takes precedence. For more information, refer to the IDOL Server Reference.

For a full list of event types that you can use in the filter parameters, see Document Tracking Event Definitions.
