Search kibana for entries logged today (relatively) at a particular time

I want to search my logs in kibana and save the search to monitor logs daily. So the query should always show today's data for a particular hour. I can save a search which shows today's data but not I'm sure how to add a filter for hour relative to today's date. Again, at any given day, the saved search will show data for that particular hour. Is there a way i can do it using querystring in kibana or the search toolbar? For e.g. see the time in below query (this obviously doesn't work, but this is what i want)
