Look at the below link, you just need to figure out the splunk search that you want. Filter on 'flower' and then do a stats count.
Something like ... | stats count by product will give you a count by all products.
I mean some detail data like the data in tutorial.
Such as the count of people who bought flower.
I get the info from https://localhost:8089/servicesNS/admin/search/saved/searches/test2 which is not the real data i want.
