Event log search multiple keywords

Can the NCC support search filters for multiple keywords?

Nebula's event logs work well in smaller sites but in larger sites that generate almost 10k logs an hour, the search filters needs improvements.

We have cases where we need to know if multiple devices are connecting/disconnecting at the same time.
But the event log search filters do not allow search of two mac addresses as a keyword.
This also means the search filter should support an "any" or "both" matching criteria.
