What is the query string format used to express filters, etc?

Hi Kibana experts,
I need to parse the query string used to specify date ranges and filters within Kibana's state URLs. Is there a standard format this string follows?
Best, Dan.

Someone must know :smile:

Its Rison :slight_smile:

Thanks, I'd never have figured that out!

PS There's even a Jackson module for it. I'm super-delighted.

I just "borrowed" the rison.js from the kibana source :innocent:

I had been going through the source but was getting waylaid by Node's querystring stuff.

Hopefully I won't have to borrow it into Java, as there's even a Jackson module for it. I'm super-super-delighted!
