 ## Crashes {#crash}
 
-A _crash_ is when the application had an explicit unhandled error or hard crash. You'll typically be able to view the corresponding issue that captures this event in [sentry.io](https://sentry.io), and errors that did not cause the end of the application should not be included. To search for crash events in **Discover** or on the **Issues** page, filter by `error.unhandled:true`. The number of unhandled events is not expected to match the number of crashed sessions because sessions are not subject to [inbound filters](/product/data-management-settings/filtering/) or [sampling](/platform-redirect/?next=/configuration/sampling/).
