Kibana search for past 2 hrs

Hi

I have a requirement to compare averages for a metric over the past 2 hours to the average for the day. In ElasticSearch I can query an index for the past 2 hours but I don't see how to create a search in Kibana that would accomplish the same thing.

My idea was that if I could create a saved search in Kibana for records created in the past 2 hrs I could create a visualization off of the search and display it next to a visualization built off of the larger index.

Is there anyway to accomplish this?

Thanks

You can't currently do this in KB.
Timelion may be more suitable though.
