Enhance "Logging" (Logbook) with free-form search field

At this moment, in the logbook you can filter based on “Entity” (and offcourse the date/time field). However suppose you want to search for specific keywords in the logging (eg. dead, unknown, unplugged,…) to quickly search across all entities. So an additional box where you can put in a string value would be great to look more granular for something.

This one’s killing me, coming over from OpenHAB where I could always filter the events.log file.

Is there a workaround? Even if it’s just filebased?

The home-assistant.log has way more output than is useful, but maybe there’s a grep regex I can use for just state changes?

Or is there an add-on that sends just state-changes to syslog?
