Grafana tempo search for event attribute

I use Grafana tempo 1.5 and and I am having a hard time using search feature .
We add events attached to spans to report errors during the span operation.

Events also have tags just like spans (normal in otel) . We store the error message inside the event . A span can have multiple errors , so multiple events attached to the span ant different timestamps.

Is it possible to search for Event data ? Will it be possible to search for event data with regex or contains in TraceQL ?
