Filter events by breadcrumbers or other additional info


I have a huge Python app. Imagine, I have some exception, which has different contexts, currently it is “Unknown error” (too many non-obvious exception might happen). So, the only thing which can help to find the reason - full traceback. And I don’t want sentry shows all of them, I’m interested only in Unknown error with some specific traceback.
Is it possible to filter events on UI somehow? Maybe by breadcrumbers, maybe by exception message (regex or so)?
