I notice that the format of the discover URL parameters is [RISON](https://github.com/Nanonid/rison), but there is no documentation around the structure of this object. It doesn't appear to be a raw ES query object converted from JSON to RISON. Aside from reverse-engineering by reading the source code - is there any public documentation available for this? I'm trying to figure out how to programmatically generate a Kibana Discover URL based on this structure. My use-case is: 1. ELK is aggregating log information to a central place. 2. An error occurs on an application server. 3. An email is sent with the corresponding Kibana Discover URL which narrows down the time-frame and applies some filters. 4. An engineer clicks on the URL and is able to quickly get the log information they need to debug the situation. I think for now, I would just create a template URL by looking up a particular issue and extracting out the necessary parameters for my particular use-case. But the parameter has a very rich syntax for describing the query and filters - so I'd like to know more about it to take full advantage. ---

I don't believe the URL structure is formally documented. It's a good idea though - would you mind adding a new issue to our Github tracker? [https://github.com/elastic/kibana/issues](https://github.com/elastic/kibana/issues) ---

Good idea. I've created issue [#4338](https://github.com/elastic/kibana/issues/4338) ---
