Sensu Events API, Search queries

Question

I've just started using Sensu, I know we have an Events API, where we can retrieve events. Since I'm used to Splunk, I used to run search queries to retrieve events. I'm trying to do the same here, Say I got the event below, how will I use Sensu Events API retrieve all the events that has "SN": "1234"? Can I ? if so how?

Thanks, Snabel
