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.

Thanks, I'd never have figured that out!  
Dan.

PS There's even a [Jackson module](https://github.com/bazaarvoice/rison) for it. I'm super-delighted.

I just "borrowed" the rison.js from the kibana source 😇

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](https://github.com/bazaarvoice/rison) for it. I'm super-super-delighted!
