Search by tags in related events

Hi there. I have one question - i need to sort all related events in event by tag value.
All of related events have tag variantId, and i need to find only of current id, can i do that with ui? Or there is any other ways to do that?
When i’m printing in search smth like variantId: “qweqwe” (existing variant) - i always get “Sorry, no events match your search query.” How i should write query to find them? Or could i export all related events and manually search.

That should work actually (just like it would in the issues search), but it’s possible there’s not actually a stored event due to how Sentry’s sampling works within an issue:

The other possibility, if you do see an event with the matching variantId, is that there’s an issue in Sentry and we failed to index it.
